Origin Version (Select Help-->About Origin): 7.5G SR3
Operating System: w2k

Dear forum,
When I try to add more than 543 filenames to a StringArray, it doesn't work and the
array is just empty. With 543 it works fine, if I select one more file it doesn't work
anymore. Can anyone explain to me that strange behaviour?

Here's some code:

	int iNumSelFiles; 
	StringArray saFiletypes, saFilePaths; 
	
	// ask user for the files to import
	saFiletypes.SetSize( 2 ); 
	saFiletypes[0]="[data (*.txt)] *.txt"; 
	saFiletypes[1]="[all (*.*)] *.*"; 
	iNumSelFiles = GetMultiOpenBox( saFilePaths, saFiletypes );

Cheers Armin

You were right, cpyang.

I worked around that by selecting a directory now and simply import all files in there (this was basically what I wanted to do).

Thanks for the explanation Mike.
Cheers Armin

I use (successfully) StringArrays with thousands of elements and agree that the problem must be with GetMultiOpenBox. If all files are in C:\Temp\ you can test StringArray with this...

string strPath = "C:\\Temp\\";
StringArray saFiles;
FindFiles(saFiles,strPath,"txt");
out_int("nFiles=",saFiles.GetSize());
out_string("last file="+saFiles[saFile.GetSize()-1]);

...The Release Notes for Origin 7.5 SR5 lists the following fix:

The Origin C GetMultiOpenBox method now works correctly to open multiple files. An internal buffer size has been increased to allow more files to be selected. (ID 5957)

I don't think so. But I'll check today.

This must be the limitation of GetMultiOpenBox, not the limitation of StringArray.
