in one sentence.
Semaphore can be used to manage resources, criticalsection to synchronize access to shared data within same(single) process and mutex to synchronize access to shared data among different process also.

Hello Friends,
I got a problem.
I had splitted the actual view into 4 parts. every view is been derived from different view's class.
The main problem is the one splitter window which has been derived from the FormView has got 2 edit boxes which will resizing itself based upon the size of the window. and when I click in someother view some message has to be displayed in these edit boxes. for example when I click in View1 then some message which I pass from View1 has to be displayed in the edit boxes present in the View2.
I am trying but its always giving me assertion failed and when I debug it its giving the asserting failed in the SetWindowText message. I had created 2 different variables of type CEdit.

I am getting the assertion failed in the winocc.cpp at line 229, When I am using the SetWindowText

Get the view address using GetActivePane() function and use it for setting the window text using setwindow text function
eg.
CMyView *pView = (CMyView *) mysplitter.GetActivePane();
pView->SetWindowText("Hi");
|

Its giving me a problem at the SetWindowText message in the Winocc.cpp file.

Check the view's pointer's value @ debug mode. Also you can use the GetPane to get the view's pointer. Have a look @ msdn.

Hi Jain
Here i do consider that i am having two panes ie two views, first the CCallManagerView(0,0) and the other CUserView(1,0). So when i do need to set some value to the CCallManagerView's control from CUserView, i'll be using the following code
void CUserView::SetValue2Manager(void)
{
CMainFrame *pMainFrame = (CMainFrame *) GetParentFrame();
CCallManagerView *pView = (CCallManagerView *)pMainFrame->m_wndSplitter.GetPane(0,0);
if (pView)
{
pView->myEdit.SetWindowText("Hai From Call Manager");
}
}
Hope this may help you. If you want the CUserView then use GetPane(1,0)
Sujan

It looks like microsoft stopped providing the DDK for download. Does anyone know where else this can be obtained?
Thanks,

Good Day
I have a device that upon plug into USB, loads the driver USBAudio.sys. I wish to develop a GUI for my device.
How can i go about doing it? Is there any info about the USBAudio.sys which i can reference?
Is there anyway which my GUI can directly interface with the USBAudio driver to pass data from GUI to USB to my device?
Thanks!

I want to open a pipe to the usb port and write some data. Can someone point me in the right direction?
Thanks,
Jill

I don't have a big experience with USB but I'm using a USB device and for this one, they provided a device driver that is used to communicate with the device. I can send control codes to this driver using the DeviceIoControl function. These control codes where also provided by the manufacturer of the USB device.
So every action (open a pipe, write data on this pipe, read data, ...) is performed via this function. I open the device with the CreateFile function.
Hope this helps...

I have source code for a program that I want to run on several PC's. I only have one PC with Visual studio so cant just re-compile the code on all the PC's.
I have tried just copying the .exe file generated by visual studio to all the PC's but the program does not seem to work properly. I am told this is because the .exe is dependant on a few .dll files.
I need to know how to package the .exe and the .dll files together to be installed on several PC's.
I think in Visaul Basic I could use the Package and Deployment Wizard, is there an equivalent to this in Visual C++?
I have not been able to find anything helpfull on the internet, so if anyone has any suggestions, please let me know.
Cheers

Gee, it's kind of hard to know what your program needs, if you're not going to tell us what it uses.
There is a program called 'Depends' ( from memory ) in the stuff that comes with VS, it might tell you waht you need. If you use MFC, you need the MFC dll, if you use C in your program, you'll need MSVCRT, etc.
I assume it's a release build ?

Sorry Christian, I didnt write the code so I dont know what it uses. like I said, I am vey much a beginner and the code is way over my head.
Thanks for the help though. Where can I find those dll's that you mentioned?
|
|
|
|
|
Windows/System32 is where they need to end up, and where they will be to start with.

How do I replace the msvcrt dll. When I try to copy the new one into the system32 folder I get a message saying that It cant be done because windows is using the dll.

If it's already there, it's already there.

no error messages, just not functioning quite right.

Then you have the dlls you need, but the code is broken.

Cheers Mike, and thanks everybody else for your help.

If you used Visual Studio 2003 and using .net, then your program will not load if .net framework is missing from the computer.
Mostly these things happen because the environment on which the code was written has some dlls in the computer which are missing from that where it is deployed.
I suggest you start by installing .net framework on the machine where you want to deploy your program.
