    - Scrolling larger "canvas" Thanks; my experiences bear out your statements. However, I wanted to keep most of the good things that the Panel control and standard containers provide, like clipping. I just discovered that if my panel implements the IContainerControl interface (e.g., public class GPanel : System.Windows.Forms.Panel, IContainerControl ), then my contained controls are selected correctly and I can suppress the invocation of ScrollControlIntoView ! This makes everything better. Before, I was using OnEnter / OnLeave events, and scrolling interfered badly-- the OnLeave event never happened after a scroll operation. I need consistent UI cues, and now I can have them. Tag: Windows Forms General Error dialog in PropertyGrid Windows Forms

    - How to change appearance of toolstrip overflow button? Hi there I derived my own class from the toolstrip, to implement a few changes. My toolstrip uses a blue background color. This works fine, but i got a little problem: The overflow button is nearly invisible, until you hover over it with the mouse. It uses the same background color as the toolstrip and only has this little black arrow which is nearly impossible to see with the blue background. I only want to get this button better visible! I tried to change the BackColor and ForeColor properties of the overflow button (which is accessible via toolstrip.OverflowButton), but ForeColor changes nothing at all and BackColor only draws a little line on the button in the desired color. I also tried to write my own ToolstripRenderer. I override the OnRenderOverflowButtonBackground, but then i have to draw the entire button by myself, which is not what i wanted. Tried to do something with ButtonRenderer.DrawButton() but this didn't work either. Any help would be appreciated! Tag: Windows Forms General Error dialog in PropertyGrid Windows Forms

    - Re-Creating the TaskBar and Visual Styles Implementation I am trying to re-create the taskbar exactly as it is now. I don't need the start menu, quick launch, or tray (yet) but just the part that displays application buttons. I was using visualstylesrenderer but it does not contain styles for the buttons in their normal state. It does contain them for flashing state. I ended up getting the image directly from the resource file and this seemed to work until you stretch the image to fit the buttons size. It then becomes blurry and ugly. Is there a better way to do this and if not how would I go about stretching the taskbandbuttom bmp so that it looks right. Is there a method for creating a taskband already that does all this for me or not Tag: Windows Forms General Error dialog in PropertyGrid Windows Forms

    - Memory usage of ListView's LargeImageList, when using OwnerDraw and DrawItem event What you see is correct that large objects are not being freed like their smaller brethren. What I believe you are running into is that the objects you are working with are greater than 85K and objects of those size are being created in the Large Object Heap (LOH). The LOH is not as aggressively garbaged collected as the standard heap and it sounds like you are quickly running out of memory. Here are your options Reuse the image that was created by placing the new image within it. Check for any possible out of memory issues nd work around, that exception from happening by testing the memory footprint before committing a big object to be created. See the article MemoryFailPoint Class with its excellent example on its usage. That will help avoid and work around memory problems as memory is being allocated and disposed dynamically. Whats wrong with stock answers. <g> Good Luck HTH Tag: Windows Forms General Error dialog in PropertyGrid Windows Forms

    - .NET app checks for original install location before running? MSI shortcuts are different - invoking them goes through some internal checking that the product is installed correctly. If not it goes into repair mode, then your shortcut target gets called. The interesting question is why it appears broken. It may be that you intentionally changed files/directories, or something else is going on and it's broken. Repair via shortcuts can be turned off with setting DISABLEADVTSHORTCUTS to 1 in the Property table of the MSI file with Orca. Although that makes most people happy it's no guarantee that a repair won't occur. There are repair options in Add/Remove Programs, other entrypoints in setups apart from shortcuts that can trigger repair, and the possibility that some other product could change your product files and trigger a repair. Windows Installer just works like that, it's framework that imposes some rules, repair is built in, and discarding the original install source MSI file is a potential problem with repair. This mechanism really is aimed at end users so that (among other things) accidental removal of files doesn't make the entire product unusable. I don't understand what user choices have to do with the repair issue. It's just a question of extracting to some non-temp location. I've done something similar, in one case with a self-extractor to the Program Files folder\Company\App that then launched setup.exe. In another case I packaged it all in another MSI file called "App Setup" that installs the setup files with a shortcut to setup.exe to install the app, they use the shortcut to install the app. . There are about 20 tools to build MSI files: http://installsite.org/pages/en/msi/authoring.htm Tag: Windows Forms General Error dialog in PropertyGrid Windows Forms

    - UserControl with ComboBox Hi Callavin, The FormatStringEditor is marked as internal which means that it can only be used from within the same assembly file, being System.Desgin.dll. Therefor it is not possible to use it like this. If you want to have the same functionality as the FormatString dialog box, you will need to create it yourself by using the UI Type Editor.

    - list view set focus to item Sort of an aside about StringBuilder ... You don't need to use StringBuilder to manipulate strings. VB and C# share the same core set of functionality. If you want to concatenate strings together then use +. You should only need to use StringBuilder when creating complex strings that include formatting. This provides for better memory management. VB has the same requirements. Here are some examples: //Simple concat string str = "Hello " + strUserName + "!"; //Formatting string str = String.Format("Hello {0}! It is currently {1}.", strUserName, DateTime.Now); //Complex (optimize memory usage0 StringBuilder bldr = new StringBuilder(); bldr.Append("SELECT "); foreach(string column in Columns) bldr.AppendFormat(" {0},", column); bldr.Append("FROM "); foreach(string table in Tables) bldr.AppendFormat(" {0},", table); bldr.Append("WHERE "); foreach(string where in WhereClauses) bldr.AppendFormat(" {0} AND", where); string strQuery = bldr.ToString(); Since strings are immutable each time you modify one a new copy is made. Concatenation inhererently creates a new string for each +. Therefore if you were to do a bunch of concatenations then you'd create a bunch of strings which is a waste. StringBuilder creates a single buffer and appends data to it. When the buffer gets full it allocates a new one. Only when you call ToString does it generate the final string. Hence it uses memory efficiently. String concatenation in C# and VB are optimized such that they will actually call the String.Concat method which internally optimizes the memory usage. Therefore when joining strings use a simple concatenation expression as it is efficient. When you need to build strings and you can't create a single concatenation expression then prefer StringBuilder . In the cases where you need to concatenate a non-string value to a string value then you can use String.Format but since it has a higher runtime cost prefer to use ToString whenever possible. The exception is for highly formatted strings where String.Format is easier to read and understand.

    - Results from a worker thread into main thread? The code is okay although the ISynchronizeInvoke cast is unnecessary. The most likely reason for this problem: it takes time for the call to be marshaled to the UI thread. By the time it is ready to execute, the NewDataSet instance is probably already cleared or disposed. Use the Clone() method to avoid this problem.

    - Windows Installer condition :Microsoft Visual Basic 2005 Hello, Thanks for the replies, I am indeed using RemovePreviousVersions which would explain the removal then reinstalling of the DBs. What I should point out is that the first version of this application went out with no conditions (lets call it Version1.0.0); on the DB files and this build I am installing is an update (lets call this Version 1.0.1). If I install 1.0.1 over 1.0.0 the DB modifications are lost from the first install, am I right in assuming this is because when installed, 1.0.0 had no condition flags set on the DBs If I build a 1.0.2 and install that over 1.0.1 then the databases are left in tact, Im assuming this is because both versions in this case have the "Not Installed" condition set. And finally, for the elite guru I have a last note: Using 5 separate PCs in a test environment, different Dell models but same build; Windows XP SP2, .Net 2.0 (including my machine that I build the project on). My machine and another will leave the DBs intact installing from 1.0.0 to 1.0.1 yet all the rest will uninstall the DBs and then install the blank ones. Again any help would be appreciated Phil Tag: Windows Forms General Error dialog in PropertyGrid Windows Forms

Hi,
When entering an invalid value in a PropertyGrid control an ugly dialog pops up telling the user that an error setiing the value occurred.
Is it possible to replace this dialog with your own implementation

You could use a TypeConverter to generate your own error message and return something reasonable back to the PG.
