• Visual Basic Vb.Net 2003

  Please i have a problem that i want to read numbers in arrays(2 arrays) and Draw Curve with this Numbers .first array is x axis and second array is y axis. and x,y axis appears in the graph as in custom component. please can anybody help me thank you The easiest way to do this is to create a form with a picture box on it, and then use the Graphics class to draw in the picture box inside its Paint event handler. I've provided a sample below. It creates an array of point structures and then passes them off to the DrawCurve method of the picture box's paint control. The sample just draws a simple curve. In your case, rather than recreating an array of point structures each time, you would want to ha ...Show All

• .NET Development WF fails to install on WINx64

  Has anyone else reported a problem installing WF on WIN2003x64 I think there is something wrong with the WF installer for x64 systems. Running the WFx64 installer fails to create the required entries in the Framework64 folder, so it does not show up in the list of installed programs. I'm using version 3.0.3807.7.

• Game Technologies: DirectX, XNA, XACT, etc. Begginers and XNA

  How hard is it for a begginger with no experience in programing and low math skills to make a working game on XNA Is it even possible How much does it take to learn C#, and how intuitive is it My first choice of program to use would be the Torque Engine, because it was implemented well in Marble Blast Ultra on Xbox Live Arcade. I would really like to be able to create games, even if simple, I also want to get in the video game industry, though not currently in programming, but I mainly want to do it as a hobby.

• .NET Development The XML declaration is unexpected. Line 1, position 3.

  A webservice calls an assembly which reads data from xml file located on the same server. But when a webservice method call is made to the assembly to read from the xml file, it throws one or more of the following xml errors, but only when the webservice is first accessed. The XML declaration is unexpected. Line 1, position 3. '<', hexadecimal value 0x3C, is an invalid attribute character. Line 1, position 6. This is an unexpected token. The expected token is 'TAGEND' This is an unexpected token. The expected token is 'NAME'. The '=' character, hexadecimal value 0x3D, cannot begin with a name. The errors occur mostly initially (when the webservice is first accessed) and then don't appear as long as no iisresets are don ...Show All

• Visual Studio Express Editions VB6 to VB2005 compile errors

  I am trying to migrate a project from VB6 to VB2005. It is about 70,000 lines of code. After the upgrade wizard completed, it gave me a UpgradeReport.htm. In this are four sections. I have 181 Compile Errors, 1431 Design Errors, 3143 Warnings, and 11 Misc. It was my understanding that if I fixed the Compile Errors, the project would compile. It does not. I eliminated all of these Compile Errors. If I try to do a build, I get 102 Errors. Of course the last one says "Maximum number of errors has been exceeded." So, I don't know if I have 102 more fixes to get it to compile or 5000 more fixes. I would like to start by just getting it to compile and then set about fixing the other things. Am I going about this the right way ...Show All

• Visual C++ stdafx.h

  How does VC++ decide whether to put a stdafx.h into your project or not I am looking at older code that I wrote a while back and I noticed that it does not include a stdafx.h I would like to add a #define _CRT_SECURE_NO_DEPRECATE 1 to stdafx.h, but the project doesn't have the file. And I'm not sure if it is safe to add it after the program has already been written. Thank you. longwood stdafx.h is generally a precompiled header, added by the VC++ project templates. Some templates (if not all) do have boxes you can to control whether or not to generate the header. See http://msdn2.microsoft.com/en-us/library/syth7b6s.aspx and the linked urls. ...Show All

• .NET Development Problem creating Zip File using Shell32.dll

• SQL Server Placing a sum in a table header column

  I have been requested to add the sum of an interger field to the table header. I have the sum in the footer (which is very easy to do), but I cannot get the sum to appear in the table header. I then set-up the stored procedure to run the sum, and place it into a dummy field. I still cannot add this field to the table header. Instead of printing the data for the dummy field (the correct total), it instead prints the actual field name on the report. Is there anyway to place a sum in a table header on a SQL Server Report Let me know. Thank you, T.J.
