Database Forum / FoxPro / Setup / April 2005MS VFP Framework Startup Problems
All I want to do is run a few lines of code at startup and I'm getting all kinds of grief from VFP8. I'm writing an app (HouseCallCID is the app) and I want it to creat a few public objects, set some public variables, etc. I'm using the VFP8 app wizard to create the folders, etc. It creates a main app called housecallcid_app which does some stuff I can't seem to wrap my brain around without reading tons of pre-generated source code. Here's the question: Where can I run my startup() procedure that sets up all my variables, etc. When I get it to work by putting it in the init() of the application object, I get "goapp is not an object" when I shut down. I get various errors when I try to put it in the housecallcid_app program depending on where I put it. This shouldn't be this hard. The one thing that MS sorely fails in is documenting their included objects, etc. (especially the framework it comes with). Is there a site somewhere that can give me a better understanding than msdn.microsoft.com (sux 4 framework)? --Mike Shull In fact "MS 'framework' sux". The great thing about frameworks is that they do a lot for you. The not so great other side of the coin is that you need to learn something else, ie how they work. If you're getting "goApp is not an object" you've inserted your call before it's being created. One of the things to knowing where things happen is that you've got to put in a lot of "DoDefault", certainly into the app init, and (usually) put your own code afterwards. I'm sorry, I gave up using the (MS) app builder too long ago to be able to remember what's where, have a poke around to find out where it's happening. Not very helpful I know 8-( Regards Mark Hi Mike, Any variable created in the init that aren't declared public are destroyed when the init finishes. Create goapp in the main.prg that loads the main form. Regards, Mike >All I want to do is run a few lines of code at startup and I'm getting all >kinds of grief from VFP8.

The goapp object is created there, and my code is definitely after the createobject () command. Depending on where I put it, it either never runs or causes errors. I'm thinking of abandoning the app wizard as a convoluted bit of code whose only purpose is to complicate things and slow down the app (runtime and development time). --Mike > Hi Mike, > [quoted text clipped - 36 lines] >> >>--Mike Shull Hi Mike, I feel your pain. In my lurking here I have learned: never use wizards or formsets, and the framework is a learning tool. I've used it too, an all you have to do is change 1 or 2 little properties ant the app breaks. Try this: In the Program Manager Code tab under Programs should be a main. If you don't have a Program manager showing click on new and select the button that doesn't show a wizard. In Program->main (New if it's not there) add two lines: DO FORM myForm READ EVENTS Close and save it as main. If it's not in bold right click on it as choose Set as Main. Create a form (not with the wiz) and add a command button with thisform.release() in its click event. Add CLEAR EVENTS in it's destroy event.Set it's ShowWindow property as = 2 (As Top Level Form) Save it as myForm. Go back to the program and highlight main and choose the run button.

However, it doesn't come without cost, and that cost is one that many people don't wish to pay. It doesn't make a framework a bad idea though. Mark Hi Mark, I agree about Frameworks, but the Framework supplied with VFP was a learning tool that was never meant to be used for production apps. The one I have most recently used is Codebook. For more info go to http://www.leafe.com , Codebook itself is available at sourceforge.net.

For an example of a simple app have a look at the one you can download from TakeNote Technologies (www.takenote.com, create a registration for yourself and go to the downloads section). Any objects or variables you create in your Main program will be visible to the rest of the app.  SignatureCindy Winegarden MCSD, Microsoft Visual Foxpro MVP cindy_winegarden@msn.com www.cindywinegarden.com Blog: http://spaces.msn.com/members/cindywinegarden > All I want to do is run a few lines of code at startup and I'm getting all > kinds of grief from VFP8..... |
