• Visual Studio Express Editions data validation of numeric fields

  I'm new to c#, testing it out on a program I was developing years ago in vb for dos!!. Currently stuck on the best way of parsing/validating a form with a dozen or so textboxes. Each box is to contain a floating point number. Do I have to repeat the try/catch validation routine for each textbox - or is there a general purpose string to number conversion that does not throw exceptions on bad data entry I do not seem able to arrive at a solution that does not require me to write more or less the same 5 or six lines of validation code for each box. Is that enough info. to get the idea of my problem Best wishes, and thanks, Ray looking at it, the button at top right shows 'unmark as answer ...Show All

• SQL Server Question about Font size

  I'm trying to set my font to any size smaller than 8. Is that possible I am trying to use portrait orientation instead of landscape but I can't fit everything on one page using portrait orientation with 8 point font. Thanks! Its not that I received an error, it's that I can't figure out how to do it. While I am constructing the report in layout view, the smallest font size available is 8. If I change the font to a 6, it reverts right back to 8. How can I set the font size in layout view to smaller than 8 Thanks! ...Show All

• Windows Forms How to set a C # form never be focused?

  Hello all, Here comes a C# Form focus controlling question. I write a C# program that only contains a form and will attach to a general process when I execute it, (e.g.: Notepad.exe) Now, the C# form can display successfully without stealing the focus from the Notepad process, i.e. show-no-activate, by using [DllImport( "user32.dll" ) ] and call the SetWindowPos as follows: {{{ SetWindowPos( handle, (IntPtr) HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE | SWP_NOACTIVATE | SWP_SHOWWINDOW ); form.Visible = true; }}} My planned next step is to prevent the C# form from getting the focus when I click on it. That is, it is hoped that the focus should be always on the attached application such as Notepad. Does anyone know how to do ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Using XNA Framework on Console App Template?

  Hi, I'm new to Visual C# (switching from Java). I came across a problem when I was trying to add the XNA framework into a console application. First thing I did was added these references to my references in the solution explorer: Microsoft.Xna.Framework Microsoft.Xna.Framework.Content.Pipeline Microsoft.Xna.Framework.Game Afterwards, I created another class which inherits Microsoft.Xna.Framework.Game, and included all the 'using' statements for the XNA framework. But when I added an image (.bmp) to my project, the properties of the image did not have the 'XNA Framework' category (which includes Asset Name, Content Importer, Content Processor, etc..). Here's an image to show the two different properties I'm getting with the two different ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 2D Doom/Wolfenstein 3D Ray Casting, how can it be done in C#?

  I searched on here for anything about this and all I've come up with is information for 3D examples, now I don't want to try my hand at a 3D FPS but wanted to experiment with the old 2D Raycasting technique, are there any tutorials or information for simple raycasting math in C# Paradoxically, I think you'll find the easiest way of making a Wolfenstein style game these days is just to use regular 3D meshes with textured polygons, and just not include any slopes in your floors or ever tilt the camera! Modern hardware (and the XNA libraries) do a ton of stuff to make rendering 3D meshes easy, so if you build a level in a modelling tool, you can render it really quite easily to the screen.

• SQL Server Performance in SSIS

  Hi: I've written new SSIS packages to do what DTS packages did and the performance I'd say is about 20 times slower. In this package, I have a loop that loops through different servers based on server entries in a SQL database. Each loop pumps 10 tables. The source query is set by a variable and the destination table is set also by a variable, since all this data goes to the same tables on the SQL server and the definitions are all the same on the source server (Sybase). It's still going and has taken about 12 hours to pull roughly 5 million records. The source query ends up being: SELECT *, 'ServerName' FROM SourceTable1 WHERE Date >= Date The 'ServerName' , the "sourcetable1" and the "Date" are all set ...Show All

• Visual Studio Express Editions cannot convert from string to integer

  I am having some difficulty with my code. When I run the program, the Sub tells me the values(ie: RECash2,3,4,&5) are "". Only RECash1 is "0". When I change the values during debugging and continue, the program runs fine. My problem is that I cannot get the values to save after changing them, or to change them before running the program. Any help would be appreciated. The code I have is: RECash1.Text = "0" RECash2.Text = "0" RECash3.Text = "0" RECash4.Text = "0" RECash5.Text = "0" RECash6.Text = "0" RECash7.Text = "0" RECash8.Text = "0" RECash9.Text = "0" RECash10.Text = " ...Show All

Any suggestions I could locate only a similar option in Report Designer Thanks Well, this will do the trick but the standard textbox wont. You may have used a 3rd party custom control to achieve it in the past - only you would know. There are numerous suppliers of controls which may serve your purpose.
