Thanks, Ji ...Show All

• Visual Basic Problem with Me.close

  Hi, I'm just moving from VB6 and have a big problem with the Me.close() function. Here is my example : The default start form is a splash screen ; name it Splash.vb which as the same function than the Microsoft Word one, for example. After a few seconds, I want to close it and load the main form, just name it Choices.vb . The problem is, when I put the Me.close() function in the Splash.vb form, it just closes the program. Of course, I have put the Choices.show just before Me.close ; so I see briefly the main form, the the program closes. To bypass this problem temporally, I changed the Me.close by Me.hide, but this is not a good solution of ...Show All

• Visual Basic Scary- Debug is running old code. Is there a way to set the debug to completely refresh.

  I was running a misbehaving program and really couldn't find what was going on until I noticed a messagebox was popping up that I had deleted previously. Hmmm.... Without changing any of my code, I deleted all the projects .exe's in the obj and bin folders.  This cured the misbehaving program and the messagebox stopped popping. Fortunately this was a very simple application and the problem was easily found.  However, I would like to have the builds and debugs work with a complete refresh.  Is there a way to set the debug to completely refresh, so it includes the latest developed code   I.E ...Show All

• Windows Forms XP Style Controls

  I am developing a Window Forms application and want all my controls to be XP style, or even Visual Studio 2003 style. I have looked around for how to do this and found info on incuding version 6.0 of the Comctl32.dll. When I do this it works fine when my style (theme) is set to XP Style, but when I'm in Windows Classic Style it reverts to the older control styles. I know that Visual Studio's controls remain with the new XP look when I am in Windows Classic Style, so there must be some way to do this in my app. Anyone know how this is done, or if there are any 3rd party libraries that provide this functionality.

• Visual Studio Custom coloring using MPF

  The documentation mentions the following for creating custom colorable items: - Set RequestStockColors to 0 or leave it untouched (Left it untouched) - Define your own ColorableItems in the constructor of LanguageService - Override GetItemCount and GetColorableItem methods of LanguageService I followed the above steps and still the custom colorable items do not show up in Fonts and Colors property page on Options dialog box. I made sure that the names of the colorable items are different from the existing ones. I am using October RTM version of SDK. What else needs to be done Thanks in advance.   ...Show All

• .NET Development Controlling Garbage Collection?

  We have a .Net windows service running on a Windows 2003 64-bit machine whose main purpose is to cache Gigabytes worth of data and make that data available via remoting calls. Currently, the process uses 13.6 gigabytes worth of memory, storing data in three main Hashtables. The problem we're experiencing involves garbage collection. At 13.6 GB, the garbage collector seems to run about every two minutes, halting program execution for 30 seconds each time. This is a big problem due to the fact that we are going to have many client applications requesting data from this service at random times and we cannot have them time out due to the garbag ...Show All
