• Visual Studio VSS 2005 WebService problem

  Hi hi. I'm trying to use the new WebServices in VSS2005. After fiddling around, reading through the forums and doing some more fiddling I've just given up. The problem is authentication. I can open the share from my computer, open the project from the share (with the non-internet version of the VSS plugin) and open the webservice url from my computer. I've tried doing SSL, but the result is the same. If I directly open a project under source control I get "VSS Web Service could not open the database". *but* if I use Open project.. and then use the "SourceSafe (Internet)" option to navigate to the .sln file in the VSS database and open it - t ...Show All

• Visual Basic Handling of unsigned values?

  Why is this code not compiled Const UnsignedValue As UInteger = &H80004005 To make it more strange this compiles: Const UnsignedValue As Integer = &H80004005 The value is larger than Integer.MaxValue but smaller than UInteger.MaxValue.   In VB, literals (including hexadecimal literals) are considered to have type integer - as such &H80004005 is actually a negative number (representation in two's complement) - so in your first statement you're trying to assign a negative integer to an unsigned variable, and in the second statement you're assigning a valid negative ...Show All

• Windows Forms Help in my application using HelpProvider

  Hi group, I am looking for some recommandations, good advice..anything that can point me in the right direction. This is the scene: I have an application shell that gets deployed via ClickOnce. Once the application shell is started it loads several modules (plug-ins) based on what the current logged on user (customer) has bought access to. There are standard modules for all customers, customized modules for indivual customers and buyable add-on modules for all customers. Each module is an assembly. I have come so far: Help files (ressources) must be leveraged from each module. I am using the module ressources for ...Show All

• Visual C# Migration from .net to vs2005

  hello, Im writting test tools for different hardwares. I started with C# .net and everything seems to work normally. Then the company wants to migrate everything to 2005. So i opened my projects in 2005 and convert them. first of all i noticed that everything run slower (does 2005 mean better ). I have some cross threading issue but i turned the warning off with the system controls so it works like .net. And third thing which is the worst is that the program is not working with some hardware. I think the code is too slow for the hardware to respond correctly back. Is there any way to speed up the code. Im using VS2005 Professional edition. ...Show All

• Visual Basic Do MS provide an equivilent for Infragistics UltraDocManager for flyouts

  I have been working with VS.net for 3 years. I am not pleased that I have to use 3rd party tools for things I wish the product did by itself. An example is flyouts. The concept of having things flyout for the end user the way they do for the developer is appealing. In the past I have made use of the Infragistics UltraDocManager which allows me to create tabs on a form that flyout and then go away on demand. With the release of Visual Studio 2005, Microsoft has provided more functionality and it is very much appreciated. I don't know yet, however, if there is anything in VS 2005 that will allow me to do flyouts easily. If there is, I would li ...Show All
