Maybe it's flickering because the text is selected? Could try SetSel(0, 0) and then set your text.

After further thought, the standard edit box is not double buffered, so it erases the background and then draws the text, so I think that's why it's flickering. I'm not sure how to fix it.

Override WM_SIZE
In the OnSize function

if(nType==SIZE_MINIMIZED)
	//Do Something when MINIMIZED
        
if(nType==SIZE_MAXIMIZED )
	//Do Something when MAXIMIZED

Somethings seem HARD to do, until we know how to do them.

GetTextExtent() on asian edition

CWnd::GetTextExtent() or CWnd::GetOutputTextExtent() does not return the correct width of the text in asian languages OS on Windows 2K. The same works as expected on Windows XP.

I have seen this with GetWindowText() also. Does anyone know or seen this issue. What is the reliable way to correct this.

Best Regards, Madhu.

Hi,

I would like to know how to navigate from one tab page to another, as stupid as this sounds I'm struggling my butt off WTF | :WTF:

Lets say you have this code:

// Adds the TabControl to the form.
this->Controls->Add( this->tabControl1 );

// Adds the tab pages to the TabControl.
tabControl1->Controls->Add( this->tabPage1 );
tabControl1->Controls->Add( this->tabPage2 );
tabControl1->Controls->Add( this->tabPage3 );

Just to move from tabPage1 to tabPage2, if anyone can help, plz do Big Grin | :-D

First of all they aren't similar
CoInitializeEx()
Initializes the COM library for use by the calling thread, sets the thread's concurrency model, and creates a new apartment for the thread if one is required.
CoCreateInstanceEx()
Creates an instance of a specific class on a specific machine.

What parameter's are you passing to CoCreateInstanceEx()?

I dont know how to get the clsid in the server code to give in this CoCreateInstanceEx() function.
I gave clsid to register the server in my server code.
Please can u give any sample code of this function.

Structures with pointers question

26-Jul-06 18:52

Hi, Does anyone know how i can store the address of a particular node ie. "startPointer". This variable will store the address of a node so that that i can call out to the node when i need it in any of my functions. My code will have no problem if I declare the startPointer variable globally. But the problem now is that based on my assignment req, I'm not allowed to declare any variables global other than the specified ones.

struct data
{
double xstart, xend, ystart, yend; //get xstart,xend,ystart,yend values
int child, iter, width, height; //get iteration value
data* next; //pointer to next node
};data* startPointer;
...
...
main(){...

Is there any way that I could get around this?

Thanks Smile | :)

DirectSound, two devices with different frequencies

motoshit26-Jul-06 18:52

26-Jul-06 18:52

Hi there,

There's a question about DirectSound. I wanna capture sound and play captured sound at the same time with the smallest latency. So I've got two buffers - sound and capture. I created N notification points in capture buffer and I'm trying to copy data from one buffer to another... But these buffers are owned by different devices. As everybody knows, there're not two equal frequency generators... so one buffer's always slower/faster than another. There're a lot of algorithms to manage this problems, they're called Sample Rate Convertors. They remove/add some samples from/to buffer, so difference between capturing and playing sound is getting to zero. But first of all I somehow should detect how many samples algorithm must add/remove... That makes a big problem for me.... How can I do it?

Thanks for suggestions.

UVSoft.

You can catch the moved event and move it back. I don't believe you can lock it otherwise.
