VISUAL FOXPRO IN WIN95/ WIN98 1

[rajeevnandanmishra]

I have a VFP6.0 application. This application runs perfectly under WINNT/WIN2K. But when we try to run this application in WIN9X then we experienced a strange problem.

The problem arises when we follow the following sequence :

From the main form we call a child form (by clicking on a button on main form). The child form is having a button to call generic Print Form (created by us). When user click on that button the print form pops-up. On print form user click on screen button, which shows him the report (through REPO FORM <report_name> PREVIEW). He closes the report. Closes the print form and the sub form.
Now if he do the process again then after clicking on Print button on sub form, it hangs up the system.

So, what could be the reason for this. And what shall we do to resolve this.

Any help will be highly appreciated.

Check if the child forms are properly released. This is where I would start.

Thanks for your quick reply Ilya.

I have checked that and it is releasing the previous forms.

And one again i am saying (if you have missed my earlier post) that it is working perfectly on WINNT/WIN2K. Only problem is on WIN9X.

rajeevnandanmishra,
Another thread (184-239199 Set printer to not working help!!!)from march 2002, also indicated problem with reports not working in win98 and winME. I noticed that &quot;report form&quot; was used in that code also. No resolution was given.

There are several bugs listed in the Microsoft knowledge base for vfp6 and reporting. On concerns crashing fp if there are two instances of report form active at the same time. I don't know is this will help. I cut and pasted from the knowledge base.

Hope it helps,

God bless

HI Rajeev,

Quite often, one does the distribution of the executable and dont think about the distribution process, simply because it was installed earlier... etc etc.

I have found out by hard learning, that distributing the setup CD every time is the best.

Often (1) the service packs made available to user and (2) the service packs applied on the execuatble create this type of odd behavious between systems and OS. I have faced similar problems when new executables are supplied and solved them instataneouly by reinstallaing using the setup disks.

Hope this helps you ramani

Thanks all,

Specially Ramani!

I was knowing the issue that microsoft releases service packs to fix some problems. And i had searched the whole microsoft site, but have not found any patch related to my problem. I have also asked the clients if they can go for a setup-cd or not. But their answer was no (i was knowing it).

Anyway, i download/installed the SP5 for Visual Studio & Recompiled my project. Then distributed the exe & dll(s) to the client. And now, users are happy, client is happy, i am happy and all this just because of u Ramani.

I don't want to write.... But i can't restrict myself to write, that, you are great
