• .NET Development VB .net "downgrade"

  I am working on a fairly simple application using VS2005, VB code.. and Dot Net 2.0. I was shocked when I checked... the application was using something like 40 mb of ram and thats just plain *ugly* and a huge bloat factor. Is there a proper place to discuss moving these types of applications back into something like VB6, or doing something to get rid of this huge bloat Thanks! Gary 1992, Windows 3.0: 4MB ram, 250KB app = 6.25% 1998, Windows 98: 16MB ram, 1 MB app = 6.25% 2006, Windows XP: 1GB ram, 40 MB app = 4.00% You're ahead... ...Show All

• Windows Forms Tutorials on imaging for beginners

  I am trying to make a bitmap font program. I want it to allow the user to assign an image to each char of the standard ascii lineup. Then when a user types in a textbox, it will create an image based on the contents of that box. I have seen some freeware programs that do this but are harder to use than needed. I have tried to ask for the source code (since they are freeware) but the authors have refused. So I have decided to make my own. I have no idea how to create the image though. Is there any tutorials for people who have never done anything with images in vb.net before If you want more information on what I am trying to do then please ask. Thank you, Troy L. I just tried the method you posted and realized that it was kind of li ...Show All

• Smart Device Development using my .h files in C# project

  I would like to give a C# application access to constants/Structures and interfaces defined in C/C++ header files . They are use d by many other applications, and I do not want to redefine them in my C# code. How can i use my existing .h files in C# project.. I'm afraid that you will have to re-declare the types in C#... C++ and C# can be so different, that it's impossible to use C++ declarations directly in C#. You should look for P/Invoke tutorials to see, how data structures can be translated from C++ types to C# types. Here's couple: Here's introduction to Compact Framework P/Invoke, and some examples what C++ types maps directly to C# types (blittable types) http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnne ...Show All

• SQL Server auto resizing column

  hi all i am working on sql reorting 2005 how can i set the column width to autoresize depending on the maximum length of data for that column plz help me. As far as I know, there is no way to autoresize column width. The only property to account for adjusting a cell's dimensions is "CanGrow." If this is set to True, the cell will increase vertically to fit all the data. However, this only adjusts the height and not the width. ...Show All

  Where do I send DX SDK bug reports The Dec06 fxc.exe seems broken, passing the same command line that worked in Oct06 to Dec06 fxc fails to compile or even read the .fx file, it spews the command-line argument help as if you've made an argument-passing mistake (without telling you what it is!), but according to the help file all the arguments are valid! Also, the Dec06 added a bunch of new cmdline arguments with no real explanation in the documentation: /Gdp disable effect performance mode /Ges enable strict mode /Gec enable backwards compatibility mode /Gis force IEEE strictness /Gch compile as a child effect for fx_4_0 targets Can someone provide more details on these The new /LD ...Show All

• Visual Studio Windows installer problems

  I ran into some virus problems a few days ago and thought that I had fixed them.  I then received access to install Visual Studio 2005 and Windows XP PRO embed SP2.  I checked for comapatibility of XP PRO with my computer and everything checked out fine.  I was too hasty in the install of XP PRO and forgot to make a system restore point before the install.  After the install everything seemed to work just fine but then windows installer popped up.  The windows installer box just says "initializing installation" and does nothing else.  If i click cancel on the box, it says "canceling installation" but does not go away.  Eventually it will give a message that says "retry or cancel" and I hit cancel and then ...Show All
