• .NET Development Visual Studio 2003.net Databases Connection not working

  I am using Visual Studio 2003.net and trying to get connected to SQL 2005. Is this even possible to do and if not what is the best way to connect to a database with Visual Basic 2003.net. Before I was able to make a connection with VB 2005 express edition and SQL 2005 express edition but this is seeming to be a “no way hosa” kind of thing. . You may be using Visual Studio Standard Edition. If this is the case I believe Visual Studio Standard Edition database tools will only work with Access and MSDE. If you try to connect Visual Studio Standard Edition Database tools to SQL 2005 or SQL 2005 Express edition it will display an error message stating that: It is only possible to connect to SQL Server Desk ...Show All

• Visual C# Interacting with an external application (process)

  Hello! I'm trying, with VS.Net 2003 and C#, to call an external command line application and retrieve the output several times during its execution (that can be long), so I can track the process and give the user an estimated time to complete. What I did: I created a process and a timer with 500ms tick. I start both at the same time and every tick I read the process' output. The problem: everytime I try to read the output using "StandardOutput.ReadToEnd()", the application freezes and only resumes when the external application is done. Using the search on this forum I found out that I had to use "Application.DoEvents()", so the application could resume the message queue, but it didn't work. So far, that's what I'm doing ...Show All

• Visual Studio Express Editions 30 day Free Trial

  I am adding "30 day Free Trial" code to my app. I want to write out a file to a secret location with the first run date, etc. Would C:/Windows/System be a good place to put it If you want to avoid allowing the end user to reflect on your code and want to avoid the security setting issue, you could always use a webservice that you are hosting to check registration status.

• Game Technologies: DirectX, XNA, XACT, etc. Using Pixel Shader 3.0

  For another project I need to use pixel shader 3.0. When I attempted to get the effect to work in pixel shader 3.0 I noticed that pixel shader 3.0 was not working anywhere. So I even tried using the code from How to: Create Custom Texture Effects. The HLSL code is written to compile it for pixel shader 2.0. When I changed it to pixel shader 3.0 it failed. It gave an InvalidOperationException on the graphics.GraphicsDevice.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, cubeVertices.Length, 0, 12 );. When I switch back to pixel shader 2.0 the program works just fine. I added code to test which version of pixel shader I have, and I do have pixel shader 3.0 (my video card is 7900gt so it should ...Show All

• Visual C# Stream does not support seek operation?

  Downloading a bunch of *.csv files I got an exception at #69 (out of total 116): "This stream does not support seek operations."} System.SystemException {System.NotSupportedException} I am wondering if anybody could comment on that. Thanks. Thank you, Tom, I cannot reproduce the error now. I download these files about every day and so far I've done it about a dozen times. Every time this routine worked well except yesterday. It worked this morning as well. For some reason that I do not understand it broke down yesterday. I had no ime to investigate why and I did not repeat a run. I have a control indicator on my form showing me what particular file is being downloaded. You can see that the download code is in a ...Show All

• Windows Forms Scrolling a panel containing graphics

  I actually call this form from another form. When it loads I see it flicker as it paints, but then it just shows up blank. If I click on the form, then it actually redraws the graphics. The main problem I am having is in the scrolling of the panel. When I scroll it ends up a big mess and doesn't work as needed. I know it has something to do with the AutoScrollPosition.X and .Y, but I've added it to the DrawLine methods in the x1, x2, y1, y2 points and still doesn't work the way I am expecting. I just need it to scroll smoothly. Maybe I don't understand the scroll, but I thought I am still technically drawing at zero even if the scrollbar is all the way down and I have to use the scrollbar position to draw the images so it appears as if it ...Show All

I am running SQL Server 2000 using SQL authenticaiton (due to be changed to Windows authentication in the next 6 months). I have a table in my database which we shall call monthly.

• Visual C# Run without building out of date porject

  I have specifically chosen the option of "Prompt to build On Run, when projects are out of date". This used to work. Sometime ago, suddenlly IDE started to always run without prompting to build the out of date project. Does anyone have any clue Thanks. Thanks again, Peter, for following this. I thought I should make a correction of my previous posts. When I said it was working, actually I meant that VS would build the project out of date. Now, VS just starts running the application successfully built last time without building it when it has been modified, so I have to build the proejct then run it. Another instance of VS still builds a changed project before running it automatically. ...Show All

• .NET Development SQLDataAdapter gets a "General Network Error" only on the server

  My application, for the purpose of resolving this problem, is a windows console application. It connects to Oracle and gets data into a OracleDataAdapter and Dataset. It connects to a SQL server and runs simple queries, deletes, and updates ok. However, when I attempt to perform an action like da.Fill(ds,"TableName") I get the General Network Error, even though I am using an existing open connection to the database. The query that returns the data is fairly complex but the error occurs even when only one rrecord should be returned. I am using Integrated Security=SSPI;Persist Security Info=False; etc in the connection string The error occurs even using an admin account. Heres the gotcha, it works fine for me when I run it on my ...Show All
