Hello, again.

My time is nearly up on the Ultrasound GUI I've been working on, and I've got one last major feature to implement: continuous capture at a user-selected 1 to 30 frames/second rate....

Hello, everyone. It's been a while.

I'm still working on the same Ultrasound machine GUI, but I'd taken time off for summer courses. Fortunately, thanks to the help I received here, I have made...

Modified 'bSave_Click' to include pbCaptureImage.Image.Dispose() before attempting to rename the directory.

This forces the image to be removed from 'active' or 'accessed' status and lets the...

After further research, it appears that the problem is likely due to file share settings. That is to say, it is currently only allowing one process to access the file.

This gives me a few options...

I have a fairly simple set of controls that make up an image viewer.

The goal of this software is to allow image captures to be stored in a temporary directory, viewed in the image viewer, and...

Remember, companies hiring programmers want 'excellent oral and written communication skills', so I suggest learning the English language (or whatever is most appropriate) before going into the...

Okay, this is what I've done...


private void DelayAdjust()
{
System.Int64 frequ = 0;
if (QueryPerformanceFrequency(ref frequ) != 0)
{

dt.AllocateFrames(8);

I see... I've set the thread priority in a slightly different location so that the entire application runs at highest. Any downsides to that?


And while I understand what you're saying, the...

Ah, so the TOTAL time for one iteration of the loop should be 33 ms?
In retrospect, that should be a big ol' DUH on my part. Whoops.
...

I probably should've mentioned that this needs to be...

Well, it works, after a fashion.
For a 5 second run at 30 fps, the loop completes in 4.969 seconds and missed 8 frames, (0.05333 frame loss ratio) which I attribute to converting 33.3333 ms per...

Hello, again!

I was under the impression that the reason why pointers were no longer used was because C# could shuffle memory storage space around to improve performance while the program was...

Okay, I'm trying that.

However, the way this capture card works makes it impossible to have two instances of the capturing object successfully operate off the camera simultaneously.

The capture...

Thank you!

I'm not sure it's precisely what I'm looking for, but this will be very helpful in seeing where the previous version of the code is having trouble.

Hello, everyone.

I'm working on rebuilding a GUI for an ultrasound machine and magnetic position sensor.
I'm rebuilding the GUI because the previous coder's work ran too slowly, not allowing for...

Hello, all.

After trying to wade through a great deal of undocumented and uncommented code in order to speed up a frame capture rate, I've decided that, for my sanity and that of my boss and any...

You are correct in that this was probably compiled on another system.
I am not aware of updated .dlls on this system, but the issue remains: I only get the active X stuff when I try to make the code...

Actually, it wasn't.

Now, if I delete the project folder and extract the full project again, the same Null reference (or active X) exception occurs when I don't make any changes to the files.

I have a dilemma.

I have a program that I was able to compile and run successfully when I first unzipped the files, but the buttons used to do frame acquisition were hidden off to the side.
...

I believe that it is called outside frmSetup. I don't have the code in front of me (I can talk about what I'm doing, but I can't bring it home), but Thanks for the response, and I'll check into that...

Hello, all. I'm working on a new project now that I can talk about.

I've been hired to fix code that performs frame capture and magnetic sensor telemetry.

I haven't worked in C# before this,...
