hi all,
My file name is stored in a string named as filetext.If i use the printf statement to see my file name it works fine.Now i want to use the Getsavename command in origin 7 to open the save as dialog box with the default file name to save it somewhere else.If i use like this:
LT_execute("getsavename filetext *.txt");
it opens the save as dialogbox and the default file name is filetext instead of my original file name which is stored in the string filetext .
And if i use only the getsave *.txt command it opens the save as box and the list of text files after selecting and saving the file name it doesn't save anything.why it happens i don't know?
can anyone tell me how to use this command in Origin 7 to show the default file name which is stored in a string (in my case string is filetext).
Thank You,
Blank

Both GetSaveAsBox and GetOpenBox are documented in Help:Programming:Origin C Language Reference:Global Functions, but I have written this example that I hope will help you with your need.

 
void test()
{
	string strFilename = GetOpenBox("*.*");
	if(strFilename.IsEmpty()) // user cancel
		return;
	
	string strPath = GetFilePath(strFilename);
	string strName = GetFileName(strFilename);
	
	// remove extension from file name
	int nExtPos = strName.Find('.');
	if(nExtPos > 0)
		strName = strName.Left(nExtPos);
	
	// do other things in your code
	
	string strSaveName = GetSaveAsBox("*.opj", strPath, strName);
	
	printf("User has choosen\n%s\n",strSaveName);
}




You should not need to use LT_Execute to call LabTalk when Origin C functions are already available.

hi all,
i imported files using the getfile *.* command.when i selected a file from the list the name of the selected file was stored in a string.
ie:
LT_execute("%A = empty");
char LT_path[200];
LT_execute("getfile *.txt");
LT_get_str("%A", LT_path, 200);
string path = LT_path;
how to use the getsavename command to save the file name with .opj extension instead of .txt extension.I am also in confusion with using the getopenbox and getsaveasbox commands.if i use the below statement it opens the saveasbox and the default file name is also coming in the box to save ,when i press save button it does nothing.

LT_execute("getsave %A *.opj");
how to use the getsavename or getsaveasbox command to my code?

Thank you,
Blank

Have you tried the GetSaveAsBox function? like

 
void tt()
{
	string strDefaultFilename = "test";
	string strFilename = GetSaveAsBox("[my file type (*.abc)] *.abc", "c:\\c\\",strDefaultFilename);
	
	out_str(strFilename);
}



GetOpenBox, GetSaveAsBox were implemented in Origin C in the file sys_utils.c and should be automatically compiled when Origin starts. The header file sys_utils.h is also included in origin.h.
