Free OCX controls
Hi,
anyone knows where I can get some free controls for access 2.0 and access97?
What I'm looking for right now is a comfortable file open and file save dialog control.
Thanks,
Fun

Thanks Trygve,
I tried this code, and it worked great. I am willing to give you 50 points also.
Do you know if there is a windows API to capture the shutdown button when it is selected ? I want to run a batch file when windows shutdown is selected.
I offered this question in the windows section of expert-exchange, but the experts responded with sharewhare applications. I prefer to code it myself...

Thanks Trygive,
i tested the code for a few minutes and it seems to work right. So suggest as answer, I'll give you the points.
I did not have the time to study the code myself so I've got 2 more questions:
Is it possible to select multiple files (for loading)? Is it possible to select a directory (to load all files in one directory)?
Anyhow, if anyone knows some more sites with free controls feel free to send a comment, I've got another 50points to give away ;-)

Selecting multiple files works fine, as long as I only select a few records. When I select about 30 files or so (that's important 'cause I'm creating some batch jobs...) The function does not return ANY file ... Any hints?

Sorry,
fingers went faster than head. I took a closer look at the code and everything's fine yet.

Sounds great. Keep up the good work...
This question was awarded, but never cleared due to the JSP-500 errors of that time. It was "stuck" against userID -1 versus the intended expert whom you awarded. This corrects the problem and the expert will now receive these points; points verified.

Call the standard Windows File Open/Save dialog box
This can be done by either using the Common Dialog Control in Access 97 or by using the APIs defined for this purpose.

To call the actual dialog from your code, see the enclosed function TestIt() within the module or use the following example as a guideline and
Dim strFilter As String
Dim strInputFileName as string
strFilter = ahtAddFilterItem(strFilter
strInputFileName = ahtCommonFileOpenSave(Filt
DialogTitle:="Please select an input file...", _
Flags:=ahtOFN_HIDEREADONLY
Note that in order to call the Save As dialog box, you can use the same wrapper function by just setting the OpenFile option as False. For example,
'Ask for SaveFileName
strFilter = ahtAddFilterItem(myStrFilt
strSaveFileName = ahtCommonFileOpenSave(Open
Flags:=ahtOFN_OVERWRITEPRO
