• Windows Forms Easy way to format textbox without negative numbers

  It is nice in 2005 to use Bindings, Advanced for a textbox and select a numeric format.  One problem I am having, however, is that I see no way to tell VS that I want numeric formatting, but I do not want the textbox to accept numbers that are less than zero.  Is there an easy way to do this What I think would be the smartest option is what I would hope MS would provide, which is a text box class that can have filters on it based on certain logical rules. So for example, if you want the textbox to check the inputted value for only positive numbers, the control would be used something like th ...Show All

• Software Development for Windows Vista How to draw text on video

  hi, i have seen the RGBFilter sample but i want draw a changing string on the video, and the string is changed according the time. For example, when i click a button on my software, it triggers the function to show the string on the video, after ten second, i want to draw another string on the video, how to do that any suggestion is appreciated! I have seen this done a number of ways. Which way is easiest will probably depend on the type of data you are playing with (AM_MEDIA_TYPE). One (relatively) simple was is adding the SampleGrabber filter. It will call you with a pointer to the raw data. You can draw on the buffer to you ...Show All

• Windows Forms LIB's in a Windows Form?

  Hi folks, I'm just wondering if it's possible to add a LIB to a Windows Form project I want to add Shlwapi.h, shlwapi.lib so that I can access the useful functions: PathAddBackslash PathIsDirectory PathRemoveFileSpec PathRemoveBackslash PathFileExists PathFindFileName etc.... Is it possible I can't seem to figure out how to add a LIB and just adding the .h causes a whole mess of problems. Any ideas Hi Blair. I would use the System.IO.Path class, but it just doesn't have the functionality I'm looking for - specifically the functions that I mentioned above. So, does anyone know how I could add a L ...Show All

• .NET Development Policy settings

  Hi, Is it possible to apply policy settings(through policy file) in the DLL project. The DLL will be used by Windows form (client) application. I am having trouble doing this. I don't know how WSE runtime will find the policy file. Even if I set the file path in the app settings of DLL project then those settings cannot be recognized by the Main application. Is it true So DLL can access Web service but WSE settings can be applied on the calling application of DLL, or I have to do policy settings through code not from the file. Just want to know if this correct or if there is a trick available to apply policy settings through policy ...Show All

• Visual Studio Team System Web tests resulting in Internal Server error due to Invalid ViewState

  I am seeing an odd problem when testing our web site.  I have no problems navigating through our website manually from a web browser and experience no problems when creating a web test that navigates through our web site. But, when I run the web test I created, then I keep getting an "Internal Server Error" on the first server page transfer.  When I look at our server logs it indicates that the problem is caused by an invalid ViewState. But, this problem only occurs when playing back (running) one of my web tests.  The ViewState appears to be formatted correctly (it can be parsed) but the error message gives no further indic ...Show All
