- Excel automation : formating dissapears Hello, I need to format a formula in a cell on an excel sheet. I'm generating the sheet completely from code that I wrote in VB. So I figured out a way to express my formulas in such a way that I can create them programatically and interpret them later on to make them show correctly on the sheet. I need to put some parts of text in subscript. I tried it several ways: cell.Characters(st, ln).Font.Subscript = True directly in vb code will at best put everything in subscript. Another option I ended up implementing was a simple macro piloted by the two integer values that works on the active cell. It works as far as I could see but the formating dissapears once I change the active cell and it is very slow! Can anyone please help me, I need a solution for this problem before I continue coding some more of my industrial plant. Tag: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ??????

- Undo and Redo in Office automation in .Net 1.1--Urgent Help needed Your question is definitely off-topic in this forum, as it's not related to VSTO 2.0 (for VS 2005). You can try addressing your question to the office.developer newsgroups, as listed under the resources in the " Please Read First " message at the top of this forum. When you post, you need to specify HOW application.undo isn't accomplishing what you need. If what you want is functionality the object model doesn't provide, you may need to program your own "roll-back" facility. Possibly, the excel.programming newsgroup could help you, but you'll want to phrase your questions language-neutrally as the specialists there tend to be rather .NET-phobic...

- Outlook addin stops responding Are you using any threads in this process, additionally it is possible that your Program is not the cause but the traffic created between the machine and a storage such as Exchange and the timer is a potential gotcha as the user may click Quit in Outlook as your timer just kicks off, have you registered to catch events on Outlook processing things such as Explorer_close. Debug information would be useful on the machine and possibly a trace log being added to your code to allow you to log the activity and what processes are happening and see whether a certain part of your code is consistently failing, otherwise we are trying to find a needle in a haystack without more information sorry Regards Tag: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ??????

- Exchange Server, Outlook and VSTO The setup: Exchange Server 2003, Outlook 2003, VSTO 2005 SE, Visual Studio 2005, .NET 2.0, Windows XP SP2. The problem: When composing a new email Outlook resolves the email address with the user's full name (if it is known). For example, if I write the email: jsmith@company.com , the it would be resolved to "John Smith" and shown as an underlined link in the "To" text box. I have searched the web and found that it is possible to use some external libraries to get the address from the name (eg: CDO, Redemption, etc.. ). My question is whether there is a way to stop Outlook from doing this name-email resolution in the first place. In other words, is there a way to stop converting jsmith@company.com to "John Smith" Thank you in advance. Tag: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ??????

- Access controls in different document instance (VSTO 2005) Hi Maha, I am not an expert on this... but lets have a look what I have managed to do: Most important first: I only managed to add the VSTO customization while the document was still closed! 1) create new Word instance object notShow = false; Word.Document newWordDoc = Globals.ThisDocument.Application.Documents.Add(ref missing, ref missing, ref missing, ref notShow); 2) save this newly created Word instance object fileFormat = Word.WdSaveFormat.wdFormatDocument; object fileName = @"C:/" + newWordDocName + ".doc"; newWordDoc.SaveAs(ref fileName, ref fileFormat, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); 3) close the new Word instance object doNotSaveChanges = Word.WdSaveOptions.wdDoNotSaveChanges; newWordDoc.Close(ref doNotSaveChanges, ref missing, ref missing); 4) add customization AddNewCustomization("C:/" + newWordDocName + ".doc"); 5) open up again the word document with the customization attached notShow = true; newWordDoc = Globals.ThisDocument.Application.Documents.Open(ref fileName, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref notShow, ref missing, ref missing, ref missing, ref missing); My AddNewCustomization method looks like this: public void AddNewCustomization(string fileName) { try { if (!ServerDocument.IsCustomized(fileName)) { string assemblyName = @"C:/deploy/jahia_temp_v1.0_1.0.0.116/jahia_temp_v1.0.dll"; string deploymentManifestPath = @"C:/deploy/jahia_temp_v1.0_1.0.0.116/jahia_temp_v1.0.application"; string applicationVersion = "1.0.0.116"; string newManifest = ServerDocument.AddCustomization( fileName, assemblyName, deploymentManifestPath, applicationVersion, false); } else { MessageBox.Show("The specified document is already " + "customized."); } } catch (Exception ex) { ex.ToString(); } } I hope this helps!

- Fixing Bad Office.Core Refernce in xl2003 Application Add-In Hi Greg I was hoping someone who knows more about the technicalties of fixing such a problem would jump in here, once the information was available... You know that references are set through right-clicking the project name in the Solution Explorer, then going over Add Reference for Office, you choose the COM tab and select the type library you need. I think there's a "thing" with Office, however, that reverts to the newest version of the PIAs available. That's why VSTO doesn't let you install it on a machine with both 2003 and 2007 present, for example. So I think to solve your problem you're going to have to manually remove all the Office 12 PIAs from the GAC. So if removing the references to Office 12 and making sure you have the ones for 11.0 doesn't solve the problem, you'll need to find out how to strip the Office 12 PIAs out of the GAC.

The article on MSDN takes VSTO document-level project as example. Document-level project's root class is ThisDocument , so Me stands for the document. The document has a CommandBars property(same as Application's CommandBars). You are working with a Word AddIn, the root class is ThisAddIn , so Me stands for the add in's instance, you must use the Application property to access the CommandBars. Your codes are totally right! KAMACI wrote: The last thing i want to learn is that: On the SECOND line if commandBar is nothing how we can use "Add" method without "initializing" commandBar The above codes first try to get a CommandBar instance named "Test". If commandBar is nothing, which proves that the "Test" CommandBar is still not created. So we use CommandBars.Add() method to create a CommandBar, and this method returns an instance of newly added CommandBar which we assigned to commandBar variable. If commandBar is no nothing, which proves there is already a CommandBar named "Test", then we do not need to create it for a second time Thanks Ji Tag: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ??????

- Excel Edit Delete Disabled Hi Nikhil... Unfortunately, one of my customers seems to be having this problem with the VSTO 2005 SE runtime installed. While I have successfully been able to "fix" the problem by deleting the Application Data\Microsoft\Excel\ Excel11.xlb file, I can not - as some other people have posted - use the code snippet you provided, as it will reset all toolbar customizations that my customer may have done (they are advanced Excel users and have many toolbar customizations). And forcing the customer to delete this file every time they use our VSTO solution is more than just an annoyance - it is a showstopper as they will not use our VSTO solution. Do you have any other suggestions on how to fix this issue Even with VSTO 2005 SE runtime installed Thanks, Joe. Tag: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ??????

- Template changes when creating new document? Hi We have an issue that we can't seem to figure out. If we have a VSTO enhanced word template and we create a new document based upon this template - then whenever you save your document then Word asks us if we want to save the template as well. For most people in the company the template file is read-only which makes them unable to say yes (a save file dialog will appear), for the rest it's annoying since we don't want to update the template. Does anyone have any suggestions to why this is occuring As I see it, there should be no reason to make changes to the template. If the current manifests have changed - then just change that in the document created. And as I see it, the manifest information is the only part in the template that VSTO should change. I hope somebody out there can help us clarify this. Best regards Anders Tag: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ?????? Using VSTO 2005 Office

- deployment of simple outlook addin???? Hi Patrick - The process of debugging the Add-in from Visual Studio should result in the "local" copy of the add-in being installed and enabled, ie, the copy that was just built in Visual Studio in your project directory. The CASPOL would also be properly set by Visual Studio. In all likelihood, the solution continues to run because you did not execute the Build/Clean task, which should remove those entries. I would suggest reexamining your setup logic -- there's a recently updated guide to deployment as a sticky at the top of this forum. Without more information on the failure I can't be sure, but the two things I would suggest checkin are: 1) CASPOL. It's probably the most likely culprit. 2) The Registry. Settings may not be being written. Looking at the COM Add-ins dialog should give you some idea if Outlook is aware of the add-in's presence.

And I've tried rebuilding them, removing the project reference (to the Class lib) and re adding it etc. But I still get the same error.

Re: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ?????? Using VSTO 2005

Hello Billy,
booking a resource is normally a workflow.
You send a meeting request to the mailbox of the resource,
after inviting the resource to your appointment and you clicked the send button.
the script behind the resource mailbox auto accepts or declines your request.
You will receive a meeting accept or decline message from the resource.
At this point you know if it is booked or not.
So monitor the incomming Emails and check for the meeting request response message.
Does this help
Greets, Helmut
Re: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ?????? Using VSTO 2005

If the resource is set for direct booking, there will be no accept or decline message.
Re: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ?????? Using VSTO 2005

Helmut,
Thanks for the response! Thanks for ALL your other post's on OUTLOOK across the web as well!
I do not actually get an email back, I get a messagebox that will say one of 2 things,
Resource has been successfully booked [OK]
or
"Resource Name" is already booked for the specified time. You must use another time or find another resource.[OK]
So where does the mail come from, if all I see is these messages
also, do not know if this matters, but if I have the 'resource' calender open, I can see the appointment get inserted and then removed when it is already booked.
Thanks again!
BillyD
Re: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ?????? Using VSTO 2005

Again, there is no message involved. The behavior you are seeing indicates that the resource supports direct booking.

Sue,
I guess I am unsure of what you are getting at, as my original question was;
How can I 'hold' up my process untill I can get that 'confirmation' that the meeting was booked
Thanks

Re: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ?????? Using VSTO 2005
Sue Mosher - Outlook MVP
Sending of the meeting request forces the resource to be booked or the booking denied. After an item is sent, it goes out of scope. Therefore, any additional processing would have to take place by retrieving the saved appointment. I haven't done any research to see if the direct booking mechanism causes an ItemChange event to fire.

Hello Billy,
then you can use a good old Windows API calld FindWindow ... to search for the Messagebox window.
Use the Spy++ from the Visual Studio Tools to find out more about the MessageBox that pops up.
Hope this helps,

Re: Visual Studio Tools for Office OUTLOOK 2003 Resource Booking ?????? Using VSTO 2005

I actually think I have a work around/new design.
It appears that the appointment 'write' event is fired twice... during the first is when I perform my routine.
I believe if I create a seperate class that will hold these events (instead of in the main addin) I can set a flag after the first fire - then perform my own operation - after the "booking has or has not occurred.
Just an idea - need time to implement and test a dummy so... unless someone knows why this would NOT work, when I get some time I will post back the results.
