I have written some code to change the screen resolution and depth then return them to their original settings. All works fine, but the Windows taskbar moves occasionally to about midscreen. Is there a function which automatically refreshes the taskbar to the bottom of any reresed window? Or a windows function I can use to move the taskbar to the required bottom edge of the visible screen?
Many thanks

Well, after a bit of digging I found the answer myself.
SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, NULL, NULL);
You need to notify the shell of a change and force a refresh. No need to move the taskbar around yourself, Windows realises there has been a change and corrects the taskbar positioning.
All good

If I understand the question properly, you can send a header that contains the length of the packet that is arriving. So when you recieve a packet, you always read a fixed length structure that contain the length of the data arriving, then you can allocate space for the incoming data.
Does that address you question?

how can send haeder i am sending and receiving as follows
rVal=send(sock, text, strlen(text), 0);
rVal=recv(sock,data,strlen(data),0);
but i am sending text but i can not receive accurate length of text. please send me if you have any example code.
and also a another problem is i have to send to multiple cleint so which method i should apply.please reply me ASAP.
thanks

Sorry I do not have example code to send - this is something that I did long ago on a DSP processor.
What you can do is send and recieve twice, something like this:
typedef struct{
int packetId; // if this is appropriate for you needs
int len;
}packet_S;
sendHdr.len = strlen(text);
rVal=send(sock,sendHdr,strlen(packet_S),0);
rVal=send(sock,text,sendHdr.len ,0);
rVal=recv(sock,recvHdr,strlen(packet_S),0);
dataLen = recvHdr.len;
rVal=recv(sock,data,dataLen,0);
As far as the best way to send to multiple clients, I do not know. You might do well to post a separate question in the forum again.
I hope this helps.

Hi all,
I am new to C++ and I want to get the value from a text box merge it with another string and then re-populate the text box. I am using the text box in a windows form.
Here is the code I have tried but doesn't work
string S1;
S1 = this->textBox1->Text;
textBox1->Text = S1 + "Test1";
Thanks
Ben

You would be having some control for the text box.
If not go to class wizard and create it. Let us name it as tb.Now you can access the text box text by calling GetWindowText. Modify the string and use SetWindowText to set the text back to the text box
Regards

prefer the GetWindowText() and SetWindowText() that handles CStrings :
CString strMsg = <font color=gray>" World"</font>;
CString strEditContent; <font color=green>
<font color=green>
CEdit* pEdit = (CEdit*)GetDlgItem(IDC_MY_EDIT</font>);
<font color=green>
pEdit->GetWindowText(strEditContent);
<font color=green>
strEditContent += strMsg;
<font color=green>
pEdit->SetWindowText(strEditContent);

this is certainly a VB++!!

Thank you all for your replies. I see you are using SetWindowText() and GetWindowText(). In the meantime I have tried the following and it worked.
String* S1 = textBox1->Text;
textBox1->Text = String::Concat(S1, S"Test");
Am I not suppose to code like that in C++ as there are better way of doing it?
Thanks
Ben

it seems that there had a misunderstood.
you are coding for .NET framework (so your question should be asked in the C++/CLI forum).
our answer were in fact for Win32 / MFC...
so don't take them in account.

But when i used the same namespace and include the .h file in a CDialog class. An error occurred: "Already defined in CView.obj file".
HOw can I access a namespace in 2 separate classes or files?

What has threads got to do with it. There must be something wrong with your application design.
Well as far as threads are concerned you can use
AfxBeginThread(...) //for starting off a thread
AfxEndThread()//to clean up a thread.
And take a look at the CWinThread class too.

Its simple as that.. (this is a worker for you!)
in the header, declare as
UINT Threader(LPVOID p);
void realThread();
in the implementation,
UINT YourDialog::Threader(LPVOID p)
{
YourDialog* me = (YourDialog*)p;
me->realThread();
return 0;
}
void realThread()
{
do
{
}while(1);
}
then as said by drawn, you can use AfxBeginThread to start the thread
ie,
CWinThread *cwt=AfxBeginThread(realThread,this);
cwt->suspend();,cwt->resume(); ..ect then the thread is under your control

Hi,
How can i change the caption of the columns headers using the MS DataGrid 6 ?
Is there any way to find out which record is selected using the mouse click event ?
Best Regards,

There is one thing I can't figure out with VC 6.0 & ADO. How can I change the 'Background Fetch Size' (DBPROP_ASYNCFETCHSIZE) property of the recordset running asynchron? It's the number of records retrieved between two fetchprogress events. It's default is 15.
It's easy to do it in VB, but in VC++ before opening the recordset, I don't have any dynamic properties available, after executing the SQL the property is read only. I suppose if it's possible in VB it must be possible in VC++ 6.00 as well. I've hard times finding any docs about it even in SDK. As far as I know this OLEDB property is supported by the Cursor Service, which is initilaized when changing cursor to adUseClient.
Any idea?

I have a class on a library on the file Libr.h/.cpp
I build a doc/view app.
I link the header in Doc.h using #include "Libr.h",
and the code is pasted in Doc.cpp using #include "Libr.cpp".
View knows that the library exist because in View.h I have #include "Doc.h".
So I have some code that use the library in Doc.pp and View.cpp.
But the problem is:
Doc.cpp OK
View.cpp: Link error LNK2019 (functions not finded when link: but no problems when compile)
So I tried to past #include "Libr.cpp" in View.cpp, and then:
Doc.cpp: Link error LNK2019
View.cpp OK
Damn!
And this appens only with some functions of the library, and strange thing is that this functions are very very similar to other functions that haven't got any problem!!
Can anybody help me??
(sorry for the long message)
Have a nice code day

#include "Libr.cpp" is wrong.
Include Libr.h in your Doc.h & include Doc.h in your Doc.cpp
