    - Reading file line by line If you are expecting an extended character from the line to be read (ex. n, N, etc) be sure to use this: using ( StreamReader sr = new StreamReader ( <FilePath> , System.Text.Encoding.Default)) without the default encoding, those extended characters will be deleted during the ReadLine() call. It took me a day to find the solution for this. Hope this helps . Tag: Visual C# Express Edition picturebox draw everything? Visual Studio Express Editions

    - Stupid Microsoft Access 2007 Question Thank you very much for your response, I have spent a considerable amount of time working to try to get this working using SQL Server (I have Visual Studio Pro), but have not been able to get it working whatsoever (It's been quite the headache). As an alternative I was suggested Access and went and purchased it. I am a bit confused now though about this, as I am unsure of how the Access 2007 JET Database works and can't find much information on this on the Microsoft site. Thank you very much.

    - Keep a Form on Top...Sometimes In order to get the visual effect I desire, both forms need to be visible. FormBack could be considered the main application, and FormFront could be considered some kind of tool window. Think for example of using the "Save As" dialog in any program. If you switch programs and come back, you would expect the Save As dialog to still be on top. Even more so, you can't click anywhere on the anywhere on the main program untill the dialog closes. That is the effect I am trying to accomplish, but am struggling with. Sorry about my difficulty in expressing this. Does anyone have any idea how I can accomplish this Tag: Visual C# Express Edition picturebox draw everything? Visual Studio Express Editions

    - Whats wrong with my SetWindowsHookEx statement? Ok I found some source code that does exactly what I'm looking for and in studying it, I found their hook statement. //install hook hMouseHook = SetWindowsHookEx( WH_MOUSE_LL, MouseHookProcedure, Marshal .GetHINSTANCE( Assembly .GetExecutingAssembly().GetModules()[0]), 0); if (hKeyboardHook == 0) { //Returns the error code returned by the last unmanaged function called using platform invoke that has the DllImportAttribute.SetLastError flag set. int errorCode = Marshal .GetLastWin32Error(); //do cleanup Stop( false , true , false ); //Initializes and throws a new instance of the Win32Exception class with the specified error. throw new Win32Exception (errorCode); } Their entire hook is defined as a class in its own .cs file When I insert that file into my own project, add the appropriate namespace for the class, and create an instance of it, it fails to hook. The SetWindowsHookEx returns a 0 and the line Code Snippet throw new Win32Exception (errorCode); gets a popup window that breaks execution and throws me into source code window with a pop up box, title "Win32Exception was unhandled", below that in the body of the window it says, "The parameter is incorrect" (errorCode = 87 if that means anything to anyone). This part of the code might be a bug in the original source. But I'm confused as to why the hook fails in my program, but works in the program from which I pulled the .cs file from Please help me.

    - Creating a text file and writing data to it, then saving it on desktop After reading your post I decided to find out what a textwriter is exactly . The help file describe it as TextWriter is the abstract base class of StreamWriter and StringWriter , which write characters to streams and strings, respectively One being a stream writer the other being a string writer . Code Snippet Dim aStringWriter, aStreamWriter As TextWriter aStringWriter = New StringWriter() aStreamWriter = New StreamWriter("InvalidPathChars.txt") From what I gather reading the help file one writes to a string and the other to a file stream . In looking at the other part of your code textWriter1 = IO.File.AppendText(filename) Dim path As String Dim returnValue As StreamWriter returnValue = File . AppendText ( path ) It does not look to me like you have defined textwriter1 as a streamwriter rather than a stringwriter . It also looks to me like you maybe able to use a streamwriter without defining a textwriter but I don't know like I said I only look at the help files so once you have it working I would like to see what the solution was .

    - Running a program off a cd Thank you for your prompt reply, but that wasn't quite what i was looking for. The program has to be able to run no matter what the drive configuration is. So even if i use the copy file method, it still wont work is the drive isn't right. I know that i could probably count on the C: drive being the main windows drive the majority of the time, but not always. Also i realize that i could jsut copy the file to C:\ but this isn't preffered because it really should be put with the temp files. anyways, tall dude, you last post wasn't quite what i was looking for. if anyone else has any ideas they would be greatly appreciated.

Set it's Interval to 50msec to make it look smooth. Don't use it to measure time. Do that with the Stopwatch class.

    - compiling a .cpp file Create a "compatible" project type for your cpp, like Win32, Win32 console or CLR. So if you have a cpp which is not Windows specific and which is started from a command console use Win32 console project. For Windows UI apps use Win32 project. Depending on the "completeness" of the cpp, e.g. if it already has a main function or if it is just a cpp with some functions or classes you want to use, you will either add that cpp to your project or your would replace the content of the project wizard generated main cpp file. A common problem for people is the usage of precompiled headers which is enabled by default. The easies way is to add #include "stdafx.h" as the first line to every cpp file you have in that project. VC++ Express does not have MFC and ATL so samples which need those libraries won't work. Microsoft gives VC++ Express for free but they want to "push" new programmers to pick up .Net. There are some complaints about this, but well, Express is a free gift... If you want to build Win32 apps you will need to download the Platform SDK. You will realize that you need the Platform SDK if headers like windows.h are included by your cpp files. -- SvenC Tag: Visual C# Express Edition picturebox draw everything?

    - C++ Express Compiler fails after installing SP1 beta I am also getting the same problem (and many, many more). From code that compiled perfectly to 211 errors. We are using C++/CLI (against my better judgement) which has caused a few such problems. The thing I find interesting is that a lot of these errors are being thrown up in <xutility> which i'm not even including. Am I better off uninstalling the SP until there is a SP for it Edit: I should mention that i'm using VS.2005 Professional. I have been experimenting and found that if I rebuild each project individually (I have many projects in my one solution) the first few rebuild OK. However, I am still getting the same errors as above. Tag: Visual C# Express Edition picturebox draw everything? Visual Studio Express Editions

hi,
in my form i have a label with transparent as background with a picturebox behind it that has a streched image in it. the problem is that even though the label is transparent the picturebox doesnt draw the image behind the label, so there is only the control color of the form.
how can i make the picturebox draw the image "under" a different object
thanks

Re: Visual C# Express Edition picturebox draw everything?

nobugz

Add a new class to your project and paste the code shown below. Build. Use the new control instead, it is at the top of your toolbox. If you change the PictureBox image, you'll have to repaint the labels too.

using System;
using System.Windows.Forms;

public class TransparentLabel : Label {
public TransparentLabel() {
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, false);
}
protected override CreateParams CreateParams {
get {
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x20; // Turn on WS_EX_TRANSPARENT
return cp;
}
}
protected override void OnPaintBackground(PaintEventArgs pevent) {
// Don't paint background
}
}
