• Visual Basic Does calling a function from a dll created from VB class library spawn a new thread when run or it uses the thread that call it?

  Hi all Just to check, when i created a dll using the VB class library. Does the application spawn a new thread when i call function in the thread or it used the thread that call it   Regards Soon Lee typically. . . no. execution blocks until the function, actually method is the correct term, returns and the execution is in the same thread. that is, unless you asynchinvoke a delegate to the function. ...Show All

• Visual Basic Upgrade to VS 2005

  I have a functional program developed under VS 6.0. It compiles and runs. I am trying to move it over to VS 2005. I get the following error. Unregistered MSFLXGRID.OCK or missing program. Is there something about the active X control that i must install or register I thought I bought a full up version. John The flex grid is not a bought component. You should probably change your code to use datagrids, which do the same thing and a whole ton more. If it works in VB6 on the same machine, then the error is misleading, if it's registered, then it's registered. ...Show All

• Visual Studio Tools for Office How to get/calculate the character width in MS Word?

  BEFORE a lot of text strings are written to a Word file using Office Automation, I need to know the width of each string. Is there any way to do it Please note that office automation cannot be used, because the Word file is NOT available yet. Thanks. It's not really a VSTO related question, but besides that I think you are not in a position where you can determine the width of the string before knowing what font is used, the size of the font etc etc. Every font (except the fixed fonts) has its own width. A Verdana string can turn out to be of a different length compared to an Arial string. ...Show All

• Visual Studio Express Editions Standard Library missing?

  Hi, I've recently started a Univercity course and I am required to do a small amount of C++ programming such as make calculators etc. These are made in the command line part of the compiler (looks like DOS) and they run there too. My question is how do I get the standard header files in Microsoft Visual Studio 2005 Express Edition to work I mean like when using: #include <iostream> The <iostream> part appears in red and says that it can't find it. In Uni I am using the Microsoft Visual Studio.net (I think that's it's name) and it has a similar look to this one I have, but I can't seem to call upon the head ...Show All

• SQL Server Changing Connection string in multiple packages.

  Scenario: 130 dtsx packages using 4 matching connections. 3 of those connections are stored in an SSIS Configuration table in an Operational database. The last connection is in a shared data source and points to the Operational database so the packages can grab the others. Problem: It's time for deployment and all of those connections must change to production servers. The 3 are no issue, just change the ConfiguredValue in the SSIS Configuration table on the production box to point to the other production servers. However, the fourth one... I had made an assumption that when you changed a shared data source it filtered down t ...Show All

• Windows Forms Fill a rectangle without drawing border?

  I'm trying to fill a rectangle without drawing its border.  I want to fill the rectangle with a LinearGradientBrush.  Unfortunately, FillRectangle seems to use the ending color of the gradient range as a border color.  This creates a line, in the ending color, just where the beginning color first appears.  Any ideas Karen Kenworthy   Josh Lindenmuth wrote: One idea is after filling the rectangle with a brush, redraw the rectangle using a pen to ensure the border color is what you'd want.  If you don't want a border, you could use the background color as the border. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectDraw deprecation question

  From what I understand, Microsoft's definition of deprecated APIs like DirectDraw means its not being updated anymore. It doesn't mean it's removed completely from being usable. For me, I'm learning it for 2d education and the book series migrates to D3D9 later. But when I ask questions on MS's forums about DirectDraw and having a problem with an issue, I can guarantee that someone will say it's deprecated and that I shouldn't use it. But if COM is all about backward compatability and pick & choosing whatever API is needed for the project (say DirectDraw, DirectMusic, etc.), why am I being told not to use it  It's a C ...Show All

• Visual Studio Invalid handle

  I'm a long time user of VSS, and our current setup existed as VSS6d for 2 years.  Our VSS7 has been installed for 4 months and this week started giving us "Invalid Handle" errors. The files check in - but we are getting the "Invalid handle" error and then later are prompted to run Analyze whenever we use the Admin panel I've run the standard Analyze and no errors were found.  I've rebuilt the shadow directories, and am not aware of any network changes (i.e. machines, names, IP's, etc) that might impact this. The files come off the server, to my local work area, and back again, but these errors are annoying - and potentiall ...Show All
