Hello Shwetha

Do you mean you want to fill a GridCtrl with data read from a text file?

Best regards

Parse the data from the file and then direct that data to the location in the grid where you want it to go.

So far I have just used Alpha-numeric and placed the data into an edit field or label, usually running it through math functions in between.

Just parsing the data should be straight forward if the file format is consistent. If the file contains something like comma delimited data that goes into the grid in sequence it shouldn't be a problem, otherwise some logic and maybe formatting the binary data may be necessary.

Hello Shwetha

Do you mean to pass the first three lines and after that, read four columns with a 32 bits number in hexadecimal in each one, for all the rows until an empty newline is found?

No, I just wanna read that data into grid, line by line or 32bit data at a time.

I wanna know the code lines, to read the data from the log file & fill tht into the grid.

Hello Shwetha

I do not understand you very well.

However you can try this and we can modify it to get what you need:

grid.AddColumn("Data");
String data = LoadFile(AppendFileName(GetDesktopFolder(), "test2.log"));
for (int row = 0, ind = 0; true; row++) {
	int endLine = data.Find('\n', ind);
	if (endLine == -1)
		endLine = data.GetCount()-1;
	String rowText = data.Mid(ind, endLine-ind);
	ind = endLine+1;
	if (rowText.IsEmpty())
		break;
	grid.Set(row, 0, rowText);
}
