• Windows Forms Modal Dialog Box focus problems and Painting Problems

  I have written a Windows Forms application using C++ (.NET 2.0). I have encountered two problems I believe are related. The first occurs sometimes when I open a modal "dialog box", in the form of a MessageBox.Show, FileDialog or custom form using ShowDialog. The dialog box does not appear on top of my application, it is hidden and thus gives the illusion that my application has frozen (The Z-Order is not first). The second is that after displaying these dialog boxes (When they do show up on top), the controls under them do not repaint themselves, leaving "ghost" images of the dialog box that was just closed. I have found several threads on this forums posted by others who have encountered the same, or similar, problems, ...Show All

• Visual C++ ignore input if wrong

  I took everything else not relevant out. I want to avoid the endless repeating of "please enter a command". If a user puts in more than five characters I want the program to ignore it and ask only once to "please enter a new command". Actually I want it to only accept the following commands "r NNN" or r, space and three integers, p p or p m or q. If these aren't entered I want the program to ignore the command and ask once for the user to "please enter a command". From a usability point of view it should always be apparent to the user what they should be inputting. If you just ignore invalid input and don't explain what's wrong then whomever is using your program is going to get frustrat ...Show All

• Visual Studio Express Editions loading large pictures in picturebox

  Hello. I'm working with large pictures (one of them is 4021x3123) and I want to load them inside o PictureBox so the user interacts with it (draws on it). The problem is after I load the picture, when I use the scroolbar to move around it, it has that flicker effect and also the interaction with my application has a delay (it takes about 1 sec for the other controls to react). I'm guessing my problem appers because of the large picture I'm loading, so is there a way not to load the entire picture inside the PictureBox and only load that portion of the picture that is currently dispayed by the PictureBox Is there a better solution to that Thanks. The picture I used was 4021x3123. I don't think co ...Show All

• Visual Studio Express Editions How to Post Code Samples

  Hello All. For the benefit of those just starting out, and to hopefully relieve the eye-strain for those of us who might be considered by some to be Really Old Farts , I thought I would relocate some of the information found in the "Suggestions for Forums website" Forum about how to post code samples, vis-a-vis Copy and Paste operations from the Visual Studio Code Editors. If you want to paste a code sample, then in the Forums Post Editor, you have to define a code block, like so: [code language=]  paste code here [/code] Before this will work, though, you have to specify a language, in quotes , immediately after the "=" in the top tag, like "C#", or "VB", or "C++".  Now, if you want to preserve the indent ...Show All

• Visual Studio Express Editions Writing text from textbox out to a file

  FYI: I'm new to VB. I made a VB program to run a bat file that is created when you select a file. 1. I have a textbox1 that displays the address of the file and writes out the full address and file name to a bat file. 2. A button labeled browse to find the file to display in the textbox1. 3. A button that runs the bat file that is created by the textbox1. My problem is that I want to append static text before the full address of the file and after too. So the bat file would look like this: "static text that never changes" "dynamic text that changes with info from textbox1" "static text that never changes" I'm using " My.Computer.Filesystem.WriteAllText" to write the contents of t ...Show All

• Visual Studio 2008 (Pre-release) Bug? LoadSequence with LoadOption.PreserveChanges doesn't work as I am expecting

  When calling the version of LoadSequence that allows me to specify a LoadOption, LoadOptions OverwriteChanges and Upsert work as the Intellisense states, but PreserveChanges does not. According to the popup text, PreserveChanges should update the original version of the data, but not the current version. In my testing, it updates both the orignal version of the data AND the current version of the data. Am I doing something wrong Here is some code demonstrating this problem: class Student { public int Id; public string Name; private string SSN; } Student[] students = { { Id = 1, Name = "Joe Rattz" } }; Student[] moreStudents = { { Id = 1, Name = "Joseph Rattz" } }; // Create the tabl ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Render to Texture Inside Shader?

  I'm sorry if this is a stupid or obvious question, but I am completely new to shaders. Is it possible to render to a texture inside of a shader For example I want to render to a texture in the first pass and then use that texture in the second pass. I am currently using XNA's render to a texture successfully. However I was wondering if it was possible to implement it inside of a shader, because I feel it would be faster, not to mention make the XNA code simpler. My gut feeling is that it is not possible, however I am kind of confused by RenderMonkey. It uses Render Targets which appear to do what I want. However, I think it may just be doing some DirectX render to a texture operations in the background. ...Show All

• SQL Server need decimal data after division

  HI, when i divide 2 nos i need the result in decimal. always the fractional part is truncated how to get it. venp-- I don't understand what you mean. Can you explain more clearly The precision & scale of any arithmetic calculation involving decimal numbers depends on the precision & scale of the individual values. You can use CAST to get constant precision/scale but make sure you use the appropriate values. In any case, see the link below from BOL for more details: http://msdn2.microsoft.com/en-us/library/ms190476.aspx Also, each tool (ISQLW, SSMS or SQLCMD) handles the display of decimal values differently and there are often settings to control it. In any case, you need to explain your p ...Show All

• SQL Server Variables set via Script task don't change

  I've got a container with two variables: xxxNextFile and xxxLastFile , both with EvaluateAsExpression = False. My container has a dataflow followed by a script task followed by another dataflow. The first dataflow starts with ae existing raw file source from variable xxxLastFile and wants to write output to a new raw file from variable xxxNextFile . The script component then sets the value for xxxLastFile equal to the value of xxxNextFile and generates a new value for xxxNextFile . The final dataflow component does pretty much the same as the first one, i.e. it uses xxxLastFile for the source and xxxNextFile for the destination.
