Ummm... It should work... Try calling m_MessagesList.SetFocus() first.

Thanks for the help, I wasn't sure if it would work coz when I tried it with a C# program it complained of missing DLL's.

Yes, C# programs require the lastest DLLs for the .NET framework to work. But this also applies to Windows 95, 98 and other OS apart from NT.

As long as you don't use any managed C++ code, a VC7 program will run on all versions of Windows.

It should, but keep this in mind:
1. Don't use any managed extensions - these require the .NET runtime. This can be installed on NT, though, but it's too new to be there by default.

2. Statically link to the MFC and Visual libraries. Otherwise, you may find the required DLL's do not exist on an NT system, and would have to be installed.

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)

I am loading information from a inf file and modifying the window based on this. I have got most of it working except a few problems. The first being I load a 'title' into a CString and try to set the cs.lpszName equal to it, but it shows up with each character being a Ý. I'm thinking that a CString might be the wrong data type but I don't get any errors saying so.

Thanks for any info,
Steve

Perhaps you're doing

strcpy (cs.lpszName, myString);

Try:

cs.lpszName = myString.GetBuffer(0);
...;
myString.ReleaseBuffer();

I guess you're using a CString defined locally within your overriden PreCreateWindow, right? If so, try using a CString defined instead as a member of your class.

That did it, thanks. How about this, my project is based on the CHtmlView. Do you know how to get rid of the vertical scroll bar? At first I thought it would be in the PreCreateWindow there, but I could not find any parameters to adjust that.

Thanks again for your help,

Look at GetModuleFileName. It will give you the full path with the filename and extension.

Focused Based Transparency Question

I am writing a desktop-based toolbar app ( similar in design to the IE Channel Bar ) written from a App-Wizard Generated C++/MFC Dialog Project that is designed to fade down to 25% opacity when it's not being used. It's intended to do this after processing the WM_KILLFOCUS message via the OnKillFocus() Dialog Member. Additionally, it should fade it's opacity back up to 100% when it recieves the WM_SETFOCUS message via the OnSetFocus() Dialog Member. My problem is that I'm unable to get any sort of transparency to work in this situation, including the articles I've seen here at CP or the MSDN Frown | :-(

. I've thought about using AnimateWindow() but to my knowledge that only fades the window out completely or in completely, and on top of that I don't know how to implement it. Frown | :-(

If some one could provide me with a code sample that demonstrates how I could apply transparancy in this situation I would be greatly appreciative. Thanks in advance.

TCP/IP questions

How do I determine whether to use regular sockets or overlapped sockets? If I only have three or more connections connecting to my server (which I'm writing)at a time.

If I make this a multi threaded application then would I need to have events telling me that a client wants to connect?

How do I set the socket handle globally in MFC, without sticking it in my header file? So that I can pass it from one function to another...example

Handle is created in my OnOk function, how do I pass it to my OnCancel function to close the handle?

Thanks

what flavour you prefer. should be good for a first start.

make it a member variable in your class or pass it to function you call.

You would be better off making the socket a member of the class, in which you hanle your communication functions. You can use overlapped writes and reads, if you use an IOCompletionPort or WaitForMultipleObjects, so that you get notified of network events based on your pending reads/writes.

The easiest would be to have a lokk at an article here on CP by Norm Almond about creating scalable socket servers. A look at the article could give you ideas on implementing a multi-threaded server or client. If you cannot tie the code to NT, you will have to use WaitForMultipleObjects instead of the IOCompletion port

hi..
I want to change text color of RichEdit but this code didnt work.
Eek! | :eek:

void ChangeColor(HWND hWnd)
{
CHOOSECOLOR cc;
static COLORREF acrCustClr[16];
COLORREF cResult;
CHARFORMAT2 cf;

cc.lStructSize=sizeof(cc);
cc.hwndOwner=hWnd;
cc.rgbResult=cResult;
cc.lpCustColors = (LPDWORD) acrCustClr;
cc.Flags=CC_FULLOPEN|CC_RGBINIT|CC_ANYCOLOR;

if(ChooseColor(&cc)==IDOK)
{

cf.crTextColor=cc.rgbResult;

SendDlgItemMessage(hWnd,IDC_REDIT1,EM_SETCHARFORMAT,SCF_ALL,(LPARAM)&cf);

}

How to insert data to the top of exist text file?

ooosawaddee329-Oct-02 5:40

I want to insert "{" to the top of exist text file and insert "}" to the bottom of text file

Example:

If in "1.txt" has this data in it.

1234afd
daf845
dfdfa

and I want to insert "{" to the top of text file and insert "}" to the bottom of text file. So I think it should be like this

{
1234afd
daf845
dfdfa
}

I write program to do that. But my program replace "{" to the first line data of "1.txt"

So my program write this data in "1.txt"

{
daf845
dfdfa
}

Below is my program.

<br />
CStdioFile OutputFile;<br />
CString outp_filename, m_string; <br />
CFileException FileExc;<br />
BOOL bEnd;<br />
<br />
	outp_filename = "1.txt";<br />
<br />
if (!OutputFile.Open(outp_filename, CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate, &FileExc)) <br />
{<br />
FileExc.ReportError();<br />
return;<br />
}<br />
OutputFile.SeekToBegin();<br />
<br />
m_string = "{";<br />
<br />
OutputFile.WriteString(m_string+'\n'); <br />
<br />
OutputFile.SeekToEnd();<br />
<br />
m_string = "}";<br />
<br />
OutputFile.WriteString(m_string+'\n');<br />
<br />
OutputFile.Close();<br />
<br />
}<br />
<br />

Do you know how to solve my problem?
Thank you very much.
