Try having another look at ZLib. It's not that difficult. It has some examples, one of which I think is in pure C++. There are other examples such as an ActiveX version.

Hi everybody,
where do i find the RLMAN.EXE described in the MSDN to localize existing resources.
And, there must also be an UCONVERT.EXE to convert files from ANSI to UNICODE.
I have installed VC++6.0 professional, but it is not coming with it.
TIA, Chris

never heard of rlman.exe ... programming international apps means u have to use unicode from the start and use the generic text mapping functions ... as well as being aware of the small gotchas to do with the unicode versions of functions (like strlen giving chars NOT bytes)
look up UNICODE in the msdn and go from there
good luck

I'm trying to read the clw file (programatically), and when I try the following lines of code, zero bytes are read from the file:
char sTemp[255];
int nBytes = GetPrivateProfileString("CLS:CMyClass", "HeaderFile", "", sTemp, sizeof(sTemp), "MyProject.clw");
The section name "CLS:CMyClass" exists, and the key "HeaderFile" exists within the section, but my program refuses to see it.
Could it be the colon character? (I've never seen a colon used in any other section names before this). If so, how do I get around it?
If the colon character isn't the problem, what could it possible be?

You need to give the full path to the file as the last param to GetPrivateProfileString(). Using just "MyProject.clw" makes the API look in the Windows directory for the file.
The INI file APIs also have a hard limit on the file size, 32K or 64K (I forget which). Is your file larger than that?
|

Well, I gave just the filename in my example because it resulted in less typing. 
I don't know how big a .clw (class wizard) file can get, but the one I'm working on is only 2k at the moment.
I know that the file is being read correctly because I check the "General Iffo" section to find out how many classes are in the clw file and what their names are. The next step is to find out what the associated cpp/h file names are, and this is where reading the .clw file is falling flat on it's face.
I guess I *could* just read all the section names and parse them that way, but what a royal pain in the ass...

I found the problem - I had the 3rd/4th parameters in the call to GetPrivateprofileString swapped around in my code.
Duh....

I have recently subclassed an edit box,and capture the WM_CHAR events. I want the dialog that houses the edit box to know a user defined message when I detect certain string in the edit box.
How can I send a message back to dialog? I have tried SendMessage with GetParent() as a handle, but it does not work. Does anyone know how to do this? Thanks all!

Do you know how to get the working directory of a process? Do I need to access some shell objects in order to get the working directory of a process? Thanks all.
|
|
|
|
|
The current directory of your own process can be retrieved with GetCurrentDirectory. Is that what you were looking for?
|
|
|
|
|
Mike's right - though sometimes you may want to get the dir in which your app (or another) resides, in order to _make_ that the working dir (we don't always have a choice as to how our apps are invoked via shortcuts etc.).
GetModuleFileName will return the full path to the location of the exe or dll, and you can go from there.

Hi all,
Please help,
Can anyone rell me how to color text ina c++ consol application run in a dos window. I have tried all ways, and have had know joy.
What #include file and how?
Any help would be really accepted.

There are lots of great things you can do with the console api.
First you get a handle to the console:
hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
This may be 0 - as long as its not INVALID_HANDLE_VALUE you're ok. (Note - you'll need to #include <windows.h>)
Now you can set colors. This sets white text on a red background:
SetConsoleTextAttribute(hConsole, FOREGROUND_RED |
FOREGROUND_GREEN | FOREGROUND_BLUE |
BACKGROUND_RED);
I tested with printf, and assume cout is ok. You might like to investigate the fns like WriteConsole etc. Search for "Console functions" in the msdn. There is stuff for positioning too.

Hi Everyone,
How do I pass the values of a variable in one dialog box to another dialog box??
For example, let say I have a dialog box with an edit box and a button. So when I type something into the edit box and presses the button, the value of what I typed is stored in the variable for the edit box.
Then how do I use that edit box variable in a DIFFERENT dialog box? Let say I want to display of whatever I typed in the edit box from the first dialog into a List box in the second dialog box, how do I do that?
If anyone has any ideas, PLMK.
Thanks in Advance!
Steve

If the windows are active at the same time, and you can get the hWnd of one from the other (perhaps a parent/child realtionship) you might use GetDlgItem to get a handle to the control in the other window.
Otherwise, you may have to set up a var somewhere that both dialogs can access.
|
|
|
|
|
Assumptions:
1) The other dialog box is instantiated when the button is pressed.
2) Both dialogs are contained in the same process (application).
3) You are familiar enough with Visual C and MFC to make this work.
///////////////////////////////////////////////////////
Put this in a header file used by both dialog box class CPP files:
const int UWM_MYMESSAGE = WM_APP + 1;
///////////////////////////////////////////////////////
Put this code in the dialog box that has the button in it (substitute your own identifiers for the ones I used):
CMyDialog1::OnButtonPressed()
{
CString sTemp;
GetDlgItem(IDC_MYEDITCONTROL)->GetWindowText(sTemp);
PostMessage(UWM_MYMESSAGE, (WPARAM)((LPCSTR)sTemp), 0);
}
////////////////////////////////////////////////////////
Put this line in the header file second dialog box that will be displaying the text:
afx_msg LRESULT OnMyMessage(WPARAM wParam, LPARAM lParam);
You have to put this just before the line that reads:
DECLARE_MESSAGE_MAP()
///////////////////////////////////////////////////////
Put his line in the CPP file for the second dialog box class:
ON_MESSAGE(UWM_MYMESSAGE, OnMyMessage)
Again, put the previous line just before this one:
END_MESSAGE_MAP()
///////////////////////////////////////////////////////
Lastly, put a function in the CPP file for the second dialog box class that handles the message:
void CMyDialog2::OnMyMessage(int nMsgType, CString sMsg)
{
// m_MyText is an edit control declared as a CString
// value
m_MyText = (LPCTSTR)wParam;
UpdateData(FALSE);
}
=======================================================
The code above allows you to exchange data between windows/dialogs without having to setup a global variables (global var'ables are bad, mmmokay?).

I have this problem. I have CView derived class. In the OnCreate function I
create a CRichEditCtrl like this:
AfxInitRichEdit();
m_richEdit.Create(ES_AUTOVSCROLL | ES_AUTOHSCROLL | ES_MULTILINE |
ES_WANTRETURN |
WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL, rect, this, 1);
where m_richEdit is a CRichEditCtrl variable defined in the header file of
my CView class. In OnSize I set the
appropriate size of the control.
Now I have this problem. What do I have to do to print the contents of the
m_richEdit and to see the contents of this
in Print Preview. I have tried many thinks, but I failed.
Thank you very much.
