Hello, I am trying to learn C++/CLI from a text. I have downloaded source code from the books website. I then created an empty project (CLR Console App.). Now I want to add some example source code from the book: File 1. HelloWorld.cpp //OK, This I was able to add as a source file to the project. File 2. HelloWorld.obj //How do I add this? //Do I need to add this? File 3.HelloWorld.exe.manifest //How do I add this? //Do I need to add this? File 4. HelloWorld.exe //How do I add this? //Do I need to add this? shouldn't the .exe be created at runtime? I would really appreciate some input about File 2, 3, 4 with the followig caveat-- If you want to respond w/ "read the MSDN documentation" or "is this a joke question?" (which I have received in the past) don't bother to respond. I am programming as a hobby an dam grateful for any help... thanks a lot:confused:

Hello, If I declare the following (or something like this....) Graphics^ g = CreateGraphics(); Pen pen = new Pen(Color::Green) g.DrawLine(%pen, 10, 10, 20, 20); It won't work without the "%". Is this a "tracking reference"? So my question is what is the "%" really doing? thanks a lot

Thanks a lot.

I have a beginners question. What does the code look like to use DrawLine in C++ CLI? -- thanks

Thanks for your help. I also have installed Visual Studio C# Express. Maybe I should uninstall the program.

Hello, When I try to create a new project w/ Visual Studio .NET 2003 I now keep getting a a Message Box that says (something like) A critical error occurred, Automation object could not be created. Does anyone know what this means? --thanks

One version of Visual Studio (2003?) shipped with a very impressive desktop wallpaper. It was a bluish/black background with a randomly generated twisting metallic "ribbon" drawn all over the place. I think the Visual Studio logo was on the bottom left. Does anyone remember this? If so, does anyone know where I could download it? I tried Google and then MSDN, found many VS wallpapers but not this one... --thanks

Hi, I want to draw my own graphs in a WinForm, but I don't want to draw directly on the Form. Which control is best to draw inside of? Picture Box? Panel? etc... thanks for help...

Hi, I have VS Studio .NET 2003 Academic. Yesterday, when I select the toolbox option all the tools are now (either) missing or 'grayed out'. How can I fix this? I reinstalled all the disks under the "repair" option, then restarted, but the problem still persists. Also, the project I was working on was a WinForm w/ out much of my own code added.:confused: Please help and thanks for your time.....I'm wasting a lot of mine.... ps- I have also downloaded VS .NET 2005 Enterprise edition.

Ezazel Thanks a lot. I think I see the "why" ...

How do I write a "Hello World" string stored in a (*.txt) file to the Console output? using System; using System.IO; //Is this the right idea?? //Please-- show me CODE not the "just use use a "-----" answer.... namespace StreamReaderWriter { /// /// Summary description for Class1. /// class Class1 { /// /// The main entry point for the application. /// [STAThread] static void Main(string[] args) { // TODO: Add code to start application here //@"C:\Documents and Settings\Desktop\Text01"; string file_name = (@"C:\Documents and Settings\Desktop\Text01"); StreamReader fReader = File.OpenText(file_name); StreamWriter fWriter = File.CreateText(@"C:\Documents and Settings\Desktop\Text01"); //Now, how do I get the "Hello World" in the text file to the console output?? } } } thanks a lot for your help.....

I'm reading chapter 1 of Lippman's C# Primer. He talks about using the "-t" option. Could some one please elaborate what this means and why I would want to do it... thanks a lot

Hi, I want to write "Hello World" using Notepad and then create the HelloWorld.exe using the >csc HelloWorld.cs (from the command prompt). "Inside C# -- Chapter 1". 1. How should I save the file with Notepad? *.txt? *.cs? "all files"? 2. I'm almost certain that I have set the environment variables for the Framework SDK correctly. 3. I have installed on my machine VS.NET 2003. 4. The file is located on the desktop. I can use the command prompt to open any file on the desktop. HelloWorld.txt will open. HelloWorld.cs will not open (although it will create a file as a ".cs" icon) and any "csc" command will not be recognized. Any help would be greatly appreciated. Go easy on me -- I'm just trying to learn the basics -- thanks

THanks, I intentionally left them blank. I think my main confusion is the fact that I have to do all the drawing in the paint handler. Once i added the timer event I can't figure out how to tie the the paint event to the timer and the function that draws the line in the paint event. :confused:

Hi, Please see the following code below: ////////////////////////////////////////////// ..... private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e) { xOrigin = Form1.ActiveForm.ClientRectangle.Width/2; yOrigin = Form1.ActiveForm.ClientRectangle.Height/2; DrawThisLine(e.Graphics); } public void DrawThisLine(Graphics g) { Pen pen = new Pen(Color.Black, 3); g.DrawLine(pen, xOrigin, yOrigin, xOrigin + 75, yOrigin + 75); } private void timer1_Tick(object sender, System.EventArgs e) { } .... /////////////////////////////////////////// I have tried to use the timer1 object and the timer1 event but can't seem to get the line to move around on the Form1. Ultimately I'd like it to rotate around like a clock hand but at this point I'll take any code fragment just to get it in some sort of animated motion. Thanks a lot in advance....

Hi, How do do I animate the movement of a simple shape (a ball) across the client area? --thanks

Hello, Let's say I have a function, exp^x for example. I would like to draw a graph of this function in the client area of my form. The only way I can think of doing this is to write a conditional loop that will iterate through values of x within some interval and then draw the value onto the screen scaled in some way to the clientRect.Height and clientRect.Width. Question: What do I have to do to get the 'graph' to appear as one continuous smooth plot? thanks

Hello, I have a GIF that is the cover of a textbook. I want to convert it so I can store documents in it (i.e. the textbook). How to proceed? Thanks!
