I want to make the user of the program be able to type in a number and let the timer count to the number but I keep on getting the wrong output. I put a int and string variable.

You can't compare an int to a string (unless the appropriate overloaded operators have been implemented).

I suggest you keep the counter and the target value in integer format. This way you can compare them easily and perform a lot of other operations like increment easily.

You’ll need to convert from string to int, when the user enters the value. For display purposes you can either format the integer into a nice looking string, or display it directly.

There's lot of things wrong with this piece of code.

for a start, use a compiler and find the obvious ones ... and continue from there.

This is nonsense. What are you trying to do?

but the pointers are confusing

'b' is the only pointer that is being used. To reference the value being pointed to by 'b', use *b.

If an 'if' statement is supposed to execute more than one statement upon TRUE evaluation of the condition, curly braces MUST be used. Otherwise, the second statement and beyond are executed unconditionally. For example:

if (condition)
do one thing     // only happens if condition evaluates to TRUE
do another thing // always happens
do some more     // ditto

What was actually meant was:

if (condition)
{
do one thing     // only happens if condition evaluates to TRUE
do another thing // ditto
do some more     // ditto
}

Void functions cannot return values.

MDI Frame Title

Hi,

I have an MDI application, and the window title is shown as title - [filename] when a child is maximised. I want to be able to change this display to look like:

filename - title

MFC does this, but I can't seem to find how to do it in plain WinAPI or WTL. I've tried overriding WM_GETTEXT but I never get that message?!

Any ideas?

thanks,

Simon.

Hi in your view use code like this

<br />
 GetDocument()->SetTitle(strTitel);<br />

where strTitel is a CString variable containing the text to display. Of course, you also can set the title directly.

CPropertySheet woes

In my MFCApp::InitInstance I've cobbled to together a property sheet so it opens with that instead of the default dialog. I'm having problems in getting rid of the OK, Cancel and Help buttons

	CPropertySheet sheet("Test");<br />
	CFilePage files;<br />
	CAnalysisPropPage analysis;<br />
	CRecPropertyPage recording;<br />
	<br />
	sheet.AddPage(&recording);	<br />
	sheet.AddPage(&analysis);<br />
	sheet.AddPage(&files);<br />
	sheet.m_psh.dwFlags |= PSH_NOAPPLYNOW | PSH_NOCONTEXTHELP;<br />
<br />
	m_pMainWnd = &sheet;<br />
<br />
	int nRetCode = sheet.DoModal();<br />
<br />
	return FALSE;

I've tried using GetDlgItem(IDOK) but it tells me it doesnt take 1 item whereas according to MSDN it should take an int. Any ideas?

It depends on which version you are trying to use. If you are in the context of a CWnd-derived class (e.g., CMyPropertySheet), the one-parameter version will work. Otherwise, if you are in the context of a CWinApp-derived class, the two-parameter version is called.

Many thanks for the reply, I've tried the param version but I'm getting a NULL pointer when using CWnd* pWnd = GetDlgItem(IDOK); Any ideas?

Re: CPropertySheet woes

David Crow12-Aug-03 3:37

12-Aug-03 3:37

Where is this code being used? If it is on one of the property pages or the app itself, there won't be a control with an id of IDOK.

BOOL CMyPropertySheet::OnInitDialog() 
{
    BOOL bResult = CPropertySheet::OnInitDialog();
	
    CWnd *pButton = GetDlgItem(ID_APPLY_NOW);
    ASSERT(NULL != pButton);
    pButton->ShowWindow(SW_HIDE);	

    pButton = GetDlgItem(0x00000009); // Help button
    ASSERT(NULL != pButton);
    pButton->ShowWindow(SW_HIDE);	
    
    return bResult;
}

URGENT! Problem with executing batch file

HI, i have a problem:
I should write an application executing a batch file which starts an MS-Dos window (console)

a programm is runnning there.

In this console i must send commands "visk[enter]" .... wait some time .... "visreg[enter]" .... and so on...

is this possible??

I searched very much, but can't find the right thing up to now.

Is it possible with this funtions:

CreateProcess (uses PROCESS_INFORMATION, from which i can get the HANDLE
to the window (but what do i need to use? hProcess, or hThread ??

With this can i use "WriteConsole" ????

I think this only writes strings, but i need to execute the command... HOW can I do that???

also it would be good, to get the response from the console output as an errormessage in my app.

Please Help!

Hi, I did some research now in google groups and MSDN, but still cant find any solution for my problem.

The goal of the whole story is to execute batch files on a remote machine.

Wouldn't it be better to write som RPC appication? But I donm't know how to do this!!!!
Can anybody explain me how to get THIS working?

I want to execute one or more batch files on a remote machine. which are lying all in the same directory.

at the moment it is working this way:
Call a batch file which internally calls remote.exe (i noticed this is from MS!)

In the nw command prompt (which is remote.exe) enter for example "visk" which is an batch file
from the remote machine lying in the same directory like the remote.exe (which is startet as server on the remote machine)

Now i want to make a Dialog based application. simply clicking a button to execute a command, or a command sequence like "visk [ENTER] visreg[ENTER] updstat[enter] ..."

HOW the hell can i manage this??? any clue??

with RPC i can start these batch files on the remote system, but i don't get the output they provide, am i right???

PLEASE HElp, I'm getting crazy of that *g*

GetShortPathName() converts long names to short, but what has this got to do with GetCurrentDirectory()? GetCurrentDirectory() has no input parameters.

what do you mean ?

you want to optimize the generated ps file ? or tweak the printer itself ?

who's generating the postscript file ? if it's you, reviewing the code itself might be usefull.

hi i m generating the both optimized & non optimized ps files, the prob is that once the ps file is given to printer , the processor utilize too much time for processing it

there is some software like "JLYT" ( u can view its info from <http: www.hp.com="" go="" solutions=""> ) in this case the efficency of the printer is increased

i think now it is clear to u

Hi!

To detect Ctlr+A in WM_KEYUP we use GetKeyState(VK_CONTROL)<0.

How can we know that user is pressing Alt+A for example ?
