If you're using native calls to allocate memory, you need to use the same to deallocate it as well.

Hallo,
I saw that ddraw was removed in dx9, so we must use d3d to create 2d-games/graph.
Ok, I read about textures and sprite.draw2d etc.
The problem is:
I use, for test, mspaint to draw the sprite (bitmap 256 colors) with white as a background color.
I didn't understand how telle to d3d to remove the background and draw only the sprite, say a red man on white background: how can I draw only the man without the white background??? Using alpha color for black: Color.FromArgb(0xff,Color.White).ToArgb(); d3d draw the white color as a black opaque and no trnasparent, so the sprite background cover the scene-color.
In simpler words when I draw the sprite in a device cleared with color blue the result is: the device totally blue and in the middle a black rectangle with the red man inside.
Hope I explained right
Thank you

Map the network drive. Add the code to copy the file from a local drive to the mapped network drive.

how can i make my project(csharp) a service on window....which automatically starts running as the system sarts

Follow these steps:
1) Create a Windows Service project.
2) Installe the service you build. The code generated will tell you which command line to install/uninstall the service.
3) Configure it to automatical start using MMC or any other control tool.

File/New -> Project. Find the Windows Service project...
You'll probably have to start converting your code to run on a seperate thread. Windows Services normally create a seperate thread to run their code on. Do NOT just put your code in the OnStart event. You'll get some interesting errors and behaviors if you do.

Hi all,
I needed a little help with running a embedded resource i have a embedded .exe file that i want to execute during the form1_load but i looked everywhere on how to run a embedded resource but all i found was info on loading pictures that are embedded resources. Could anyone help me out please all info is appreciated.

The last post from Steve Hansen at the bottom of this article[^] shows how to extract and run an embedded exe.

Thanks for the info i was reading that and it said that it only worked for other .net applications. Is there any other methods i can use to execute a app that is not .net??

Hi all,
I have a form (we'll call form A) which I need to hide because it takes 4 seconds to load. I have created another splash screen form (Form B) to cover form A and hide it while it is taking it's sweet time being created. I have to create Form B modeless so Form A can continue to initialize. Once Form A is finished I cannot figure out a way to return focus back to Form B which is covering Form A.
Any suggestions???
BTW: This is a continuation of the OPACITY nightmare from yesterday!

Try to clarify a couple of things:

Have you checked if Form B modeless is necessary for Form A to continue?
Cubzfan wrote: Once Form A is finished I cannot figure out a way to return focus back to Form B which is covering Form A.
Do you mean "Once Form A is finished I cannot figure out a way to return focus back to Form A which is covered by Form B"?

Jun,
Thanks for the reply. Answer to the first question is yes. As I stated, if form B is Modal form A will not be created. Answer to question 2... what I wrote is correct. Form B covers Form A, I've set Form B to "Topmost" so it will reamin on top of form A.
Form B splash is only there to cover Form A while it is being created.
1. Form B comes up first (modeless to allow Form A to continue being created)
2. Form A is initialized and starts to appear behind Form B.
3. Form B has a "Next" button when clicked causes Form B to be destroyed.
4. Form A is the only thing left looking good and ready to go.
Problem is since Form A is created after Form B it has focus and will not give up focus so user can click "Next" button on Form B.
Who's on first???

It looks good, but I think the Next button is something that causes unnecessary complexity. For example, if Form A is not done initialization, the button has to be disabled. I would just get rid of the button and do the following:
When Form A is created (by Form B or any third party), pass the instance of Form B to Form A. When Form A is done initialization, it closes Form B using its instance.
A slightly different approach is starting Form A first. Let Form A create Form B to cover itself. Then Form A can close Form B whenever it needs to. This would further simplify your design.
This way, there is on focus transfer issue.
Best,
Jun

Search the articles for "splash screen" and you'll find a bunch of examples of this.

try this:
void InitMethod()
{
Form B = new FormB();
A.Hide();
B.Show();
//Initialization code...
B.Close();
//Carry on with FormA
}

i have made a program that works as follows
1->i browse some csharp project and open the main .cs file
2->the program compiles that project and reports errors as we compile in .net compiler
i want to make my program work in this order
1)select a project of csharp
2)the program should divide the project into independently compileable parts
3)then it should display a list of those parts
4)on selecting one part it should compile that part
5)then after compiling all parts on selecting one by one it should link all the seperately compiled parts to generate exe and show the output

Hi:
I am programming in C# and wondering if there is a simple way to have direct communications between 2 programs on the same PC.
Here's the scenario I am thinking of:
1. Program a and program b are installed in a machine
2. progA is launched
3. progA needs some information and launches progB if needed. If progB is already launched, progA does not relaunch progB, but uses the active instance of it.
4. progB provides the information to progA.
5. progB is available for any other program progC etc. that want to call it for information
6. progB terminates only when the machine is rebooted.
I hope my weak terminology is still comprehensible. Please could you give me tips on how to launch progB from other programs and how to leave it on (not be a child of the lauuncher), and how to initate communication with progB if an instance is already running.
Regards, smurfy

This seems to be a typical multi-process application. I prefer to implement them as server/client.
1) Build Program B as a service on Windows. Program A(or C) can easily check if the service is running. Launch the service if it's not running.
2) Implement an IPC channel between Program B and Program A(or C).

Launch Program B as a service or spawn it as a separate process. Either way, Program B will be on even when you close Program A.

Through IPC, like socket or shared memory.

is it possible to divide a large csharp project into smaller parts (at runtime)that can be compiled independently..........if possible then how to make parts and how to link those compiled parts to generate an exe of the project
jadoo

I'm not positive, but I think afte the 1st compile, only the changed parts are recompiled on build unless you specifically request a complete rebuild.
