I hope to write an application which makes an outgoing call to a
phone. When the phone is pick up a soundfile have to play over the
modem.
Please help me

You're going to need a TAPI compliant modem. Then, you need to do research on TAPI 3.0 and find some TAPI 3.0 library that you can use with C# to pull this off.

Heyy, I want to alter an image. jus need to change color of some pixels in an image. What i m doing is this:
FileStream f = new FileStream("d:\\puzzlesolver\\puzzle\\piece" + i.ToString() + ".jpg", FileMode.Open, FileAccess.ReadWrite);
Bitmap bmp = new Bitmap(f);
f.Close();
bmp.SetPixel(n, j, Color.IndianRed);
[note]: n,j are within the cordinates of the image.
but after running the code successfully m not able to change the color of the pixels...What am i doing wrong here?? pls help....
|

|
|
There's nothing obviously wrong with the code. How are you determining that the pixels don't get set??
|
|
|
|
|
|
You don't have to write any code to do this. There's something already in code keeping the process alive.
Did you use any background threads in your application at all??
|
|
|
|
|
No i haven't use any thread in my application...
|
|
|
|
|
Well, somewhere in your code your using something that's keeping your process alive. Either a component that hasn't been disposed of properly, or something else that's generating a thread that hasn't terminated, or some other external resource.

there should be the process of killing all the threads ....
if u know then please tell me .......

There is. It's called - you write the code to terminate them. Having a process that forcefully terminates running threads is a bad idea. There's a reason the thread is running, so you should deal with it. For instance, suppose your application performs an auto-save. Having the thread that performs this terminate unexpectedly would result in the file becoming corrupt - this isn't a good idea. It's up to you to find your running threads, and handle them - not for Dave to magically conjure some code up for you.

There is no code to do this. It's not just a stray thread that can cause a problem like this.
Your ONLY option is to do a code review and figure out that's causing this to happen. There's hundreds of possible causes, so noone can tell you exectly what to look for. You have to test chunks of your code to figure out what's doing this. Noone can do it for you.

Hi,
It's not clear in your post whether or not your app uses the .NET framework. If it does not then the problem may be that you have not called the win32 function PostQuitMessage in response to the WM_DESTROY message that is sent when you close the main window.
Without the call to PostQuitMessage the main message loop of your app would still be running.
Alan.
[EDIT: Ignore this, I see from your previous posts that you are using VB.Net]

Hi
I have Developed my first live project called "Library System" .
I have Developed it using Vb.net
I need some help
I don't know how to create installer for deployment of my system
|
|

So many options, but it depends on the complexity of your app:
If you created the app using .Net and aren't using any com objects, all you should have to do is COPY and paste your prog directory onto another client (known as XCOPY). You could also do a click once (do a google search) which forces your clients to update anytime you update your files.
If you are using interop objects, you can either set them to be isolated or shared (you need to ensure all clients have these interop .dlls and use regsvr32 to register them).
Depending on references, you may need to have redistributable setups or files as well - just depends on what your referencing.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

Add a new project to your solution, but choose Other Project Types --> Setup Project.
This will create an installer app for you. Give that a test run and play around with the options (desktop icons, program menu folder names, etc).

I am opening an image on a picturebox using:
pictureBox1.Image = new Bitmap(openFileDialog1.FileName);
then i am drawing some lines and curves on the picturebox using the event:
private void pictureBox1_Paint(object sender, PaintEventArgs e)
such that the painted lines and curves are drawn over the image opened on the picturebox. Now, I want to save the image containing the original image and the lines or curves drawn on the picturebox as one image. Please tell how do i do that........
Thank You

Well, the first problem you have is that you're not drawing the lines on the image. You're drawing on the surface of the picturebox control. So, everything you see appears as though you're drawing on the image when you're not.
You have to draw the lines on the bitmap you created, then you can save the changes back to the original files.
Speaking of that, you have a second problem. When you created a Bitmap object using the overload that you did, the file gets locked for the life of that Bitmap object. This means you can't save any changes back to the original file.
To get around this, you have to create a FileStream object, opening that image file, then create the Bitmap from that Stream, then closing the file. This will prevent the file from being locked so you can save the changes back to it.

Create a composite control where there is a button (or have a hotkey like a function button) to launch the common dialog control or ColorDialog - that handles opening the dialog.
Trap for when the ok button specifically is pressed and then update the backcolor on your control with the color selected by the user.
