You can use time_t & asctime (time.h)

time_t tCurrentTime;
struct tm * tmInfo;
time ( &tCurrentTime );
tmInfo = localtime ( &tCurrentTime );
cout<<asctime(tmInfo);

If you are using MFC, you can simply use CTime.

How to reterive the values from first dialog box to the second dialog box

4-Mar-09 22:12

Looks like it's a different story in WinCE. time.h functionalities are not implemented in WinCE runtime. So it looks we need to use these APIs and build our own display format:

GetSystemTime[^]

SYSTEMTIME[^]

Use the first link to get the structure filled. Using the second link, you can make out your own formated string by taking the values out of it.

Concatente two rtf string

4-Mar-09 19:23

I don't get your question. But you want to communicate with the parent dialog, you can use custom Messages and send it through parent->SendMessage(Your_msg).

We have a neat & simple article for dialog communications. Here[^]

But, explain your question better.

For the graph part, you can take a look at my sig, I developped a charting control. Maybe it could be useful for you.

Notepad is a program, it doesn't "store" any information. What you probably meant is that your information is stored in a file. Then what you have to do is open that file and parse it to retrieve the information you need. There are several options there, but I would suggest using ifstream (the C++ way).

That really depends on the format of your file.
You can look for tutorials about std::ifstream. This lets you read formatted data from a file.

I have tried with the charting control.
"Add a custom control to your dialog resource, open the Properties of the control, and specify ChartCtrl for the Class attribute. To avoid flickering on the scrollbars, you have to set the WS_CLIPCHILDREN style (0x02000000L), as shown on the image."

I don't know how toadd the custom control. I am working in VC++ 6.0, I have clicked on the insert->dialog->custom but i am not able to get any such kind of the window.As I am working in MFC ,I don't know where should I include these coding

"CChartLineSerie* pLineSerie = dynamic_cast<CChartLineSerie*>
(m_ChartCtrl.AddSerie(CChartSerie::stLineSerie));
CChartPointsSeries* pPointSerie = dynamic_cast<CChartPointsSerie*>

(m_ChartCtrl.AddSerie(CChartSerie::stPointsSerie));
" ....Please help me..

I replied in the other thread you started this morning.

Well, that really depends on what you want to do... Usually, initialization of the chart control is done in the OnInitDialog function of your dialog class. If you only have static data (everything is known when the program starts and will never change), then you can also populate the control in the OnInitDialog function.

Run swf file

i have one exe it will run SWF.

when i run that exe file it displays the .swf file.but when i call this exe for button click in MFC it doesn't show that .swf.

What is a reason?

I have called exe for button click with

WinExec("c:\\app\\Lock.exe", SW_SHOWNORMAL);

am also tried with shellexecute.

Eytukan4-Mar-09 20:21

4-Mar-09 20:21

You question is not clear, but I guess you are trying to open a SWF file. If you don't have a default viewer associated. It won't open. You need to specify the associated application as well.

ShellExecute(NULL,"open", "YourFalshViewer.exe", "c:\\YourSWF.swf",NULL, SW_SHOWNORMAL);

You may be missing the working folder of that exe.

i am not running .swf file directly.

I have an exe file that will run .swf

when i click the button it will call .exe file .

Nishad S4-Mar-09 22:31

4-Mar-09 22:31

Yes. I am talking about the same. I doubt that your exe is missing its correct working folder so that the swf file would not be available for the exe. You can use ShellExecute or CreateProcess to specify the working folder also.

sFilePath.Format(("C:\\app\\FULock.exe");

ShellExecute(NULL,"open", sFilePath,NULL,NULL, SW_SHOWNORMAL);

The APP Folder contains .swf file.

it wont display the .swf

Nishad S4-Mar-09 22:51

Try this...

ShellExecute(NULL,"open", sFilePath,NULL,_T("C:\\app\\"), SW_SHOWNORMAL);
