    - How to make a window Form stay in the same location all the time? You are right, thanks for you input. The reason our users want to do this is because, we have some windows like A shows B, B shows C. They only want user to see the top window, which is C. The don't evnet want to see A and B. So, we make all of them in the same size, and don't allow them to move. It is kinda dumm, but, clients often give us headache like this.

    - Question on setup project I am developing a WinForm application in VS 2003. I have placed the application settings in the App.config file. When I release a new version of the application, I want part of settings to get updated but not all of them. Right now, the install is replacing the old .config file with the new one. I don't want the user to enter all the settings he entered earlier. Is there a way I can programmatically merge the new and old settings Do I have to use Custom Actions Please suggest me if there is any other way through which this scenario can be handled! Also, is there any example I can look at Thanks Basani Tag: Windows Forms General Scrolling issue in Windows Forms Windows Forms

    - Display Timer The Timer component is just for counting time. The tick event is called every time a specified interval has elapsed. Example: You set the Interval for your Timer to 100. This means that every 100ms (One 10th of a second) the Timer.Tick event will get called. This way you can make a counter or anything you like that needs to be done every 100ms. In the case I supplied, you set the interval to 1000 (1000ms or One second). That means that every second the Timer1_Tick event handler will be called and in the event handler I add One Second to the TimeSpan object. So timecounter will be one second longer at every 1000ms. TimeSpan is pretty much a class that represents a period of time. As TimeDate represents Date/Time like calendar. Tag: Windows Forms General Scrolling issue in Windows Forms Windows Forms

    - Problem to manage bindingnavigator and controls binding to a dataset I have a master detail relation, represented with textboxes and comboboxes the master data and with datagridview the detail. The navigation is managed with a BindingNavigator and the data is retrieved through a dataset with both tables and the corresponding relation. The bindings are done with their corresponding bindingsource (one for the master, one for the detail and other for the relation) When I did the fisrt data population everthings seems fine, but if I reload the dataset with diferent data, the binding controls didn’t refresh their values. PLease help! Thks, Ignacio Tag: Windows Forms General Scrolling issue in Windows Forms Windows Forms

    - How do i assign items to the list box... Hi Guys, Thanks for your answers.... 1) Basically I had an array of sorted nos (Int32[]) which I wanted to assign to the list box directly without iterating through array and adding each item saperatly. There is AddRange method but it only takes array of objects as a parameters. So I guess as manju stated, we ve to iterate through the array to add them in the list box. Thank You....

    - VB.NET Windows Forms App VERY SLOW after upgrading from .NET 1.1 (VS2003) to .NET 2.0 (VS2005) I used the ListView MouseMove event (together with left mouse button down test) to track the subitem location, and then I update the datarow and listview item as each subitem is updated with the appropriate character ('B' for basic hours, 'O' for overtime, etc.) and I set the corresponding subitem forecolor/backcolor. I change the width of the subitems to 'zoom' in/out, so normally the text in the subitem cell isn't visible, hence the use of colors. In .NET 2.0, even adding items to the listview is so much slower than before and that is a simple operation. Previously, populating the listview with 100 items and validating the data took less than 1 second ... now it is taking around 24 seconds! *Edit: I go and do some more testing on the ADO side to see if that really is slower ... it is slower stepping through with the debugger (waiting for each step to be executed), but this isn't a valid test, so I'll need to re-examine this and post back here. The data validation does access the dataset and I've already timed this and it is way slower than before, so this does indicate slow ADO performance. I'm off to try and get an image uploaded ... Here is a screen capture (with real names obscured) ... http://img402.imageshack.us/img402/2405/timeline2ja8.jpg Do you need me to post some code Here is some now slow ADO code used to validate the entered schedules ...

    - FullTrust and FileIOPermission Hi all, I've got a problem here that I don't know how to fix it. I have a clickonce-deployed app that. There's a feature in the app that uses reflection to analyze types in an assembly. ClickOnce security is set to FullTrust. Everything works fine, except that the assemblies loaded by the app remain locked until I shut down the app. To fix that problem, I've created another appDomain within the app and moved the logic that loads the assembly to that sub-domain so that I can unload programmatically. Now the app doesn't work any more. Whenever it tries to execute the line that load the assembly through reflection, I get the following exception: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. If I turn off ClickOnce Security, it all works again, but of course this is not an option since that setting turns back on when I publish the app. Any ideas I've tried programmatically grant permissions to that sub-appdomain that I create, but it doesn't work either. I don't understand how it works fine when I run the logic from the main appDomain, though... Any help is highly appreciated.

    - Custom UserControl not accepting Key events I'm in the middle of writing a PacMan clone using GDI+. I've currently got code to create the maze, the dots, and the PacMan figure. I even have movement working. That is, until I tried to change the main window from a Form to a UserControl. Now I can draw everything, but the control doesn't accept the keydown event. I've properly created a handler, that isn't the problem. I believe that the problem is that Form containing the UserControl is capturing the event instead of the UserControl. How do I make the UserControl catch the event instead Tag: Windows Forms General Scrolling issue in Windows Forms Windows Forms

    - binding and uninitialised variables Hi I've hit this problem attempting to use databinding to objects via a bindingsource. When binding to a newly created object, date members and currency members display as '01/01/001' and '￡0.0' respectively, as they're already bound to the uninitialised members. Is there a way of limiting the bindingsource so that it only binds form->object thus leaving the textboxes blank I could perhaps use nullable types for the members, but is there a better way TIA Tag: Windows Forms General Scrolling issue in Windows Forms Windows Forms

    - DropDownList SelectedIndexChanged not firing I run into this bug occasionally. Today, I fixed it by fixing up some of the page HTML. In my case, I had had a table nested within a table. I ended up deleting the outer table and somehow ended up with an orphan <strong> tag above my <table> tag. In the HTML window, this is underlined in red as invalid but, of course, you never see this if you are editing in Design view and just looking at that and your compiler output. Once I deleled the bad nesting, the event fired normally. So, start by checking your HTML. Tag: Windows Forms General Scrolling issue in Windows Forms Windows Forms

If I am not misunderstand you, set the Multiline property of TabControl to true is what you need. If I'm off base,
please feel free to let me know.

Hope this helps.

Re: Windows Forms General Scrolling issue in Windows Forms

nobugz

How did this thread get marked as answered It is clearly the wrong answer. You've got the form's AutoScroll property set to True. Whenever you set the focus to a control, AutoScroll ensures the control is scrolled fully into view. There's no fix for this, consider redesigning your UI.
