ActiveX ? problems on a more powerful computer,Playsound and sendMCIstring functions

[alex_read]

You should always try and compile on the more powerful machine, these 2000 files will have some differnet calls in, while keeping backward comp-atibility with older OS's such as 95.
Doing it the other way round looses the functionality.

I tried to compile on a higher version of operating system..This would not work..

By doing some research , I have found others that had this problem with ActiveX dll's...Still no answers yet..

[alex_read]

• I take it you did use the P&D wizard for this (not mentioned abouve & forgive me if it's obvious, but I've seen posts like this in the past where the user just copied files over & this'll cause it).
• What component / add in do you use in your app to play the sound files, or do you call on the default player for them ?

That's ok, assume I don't know what I am doing..I am known for missing the obvious. Do I need to do a P&D just to use code from
machine to another? This is what I did:

I developed the code on a Win95 machine. I then installed VB6 sp5 on a Windows 2000 machine. I wanted to continue developing on the W2k machine. I copied my code to this machine and that's when all the trouble began. I have ran this on 4 Windows 2000 machines..All have failed on the same line of code. I am sure that it is related to the Playsound Function and the Mcisendstring functions because when I REM those lines out, no errors. I am playing wavs and avi's. Those functions should be compatible to Windows 2000. I will post the dump file.

That one doesn't do a lot for me unfortunatly
I've just tried this myself & it doesn't look like 2000 supports the MCISendstring command after all.
Give me till tomorrow morning to look at this as I'm running 2000 & will find a way to play this type of file ...

The attachment is an example of how I created the resource only dll. The dll I made is 64MB. It's big, but it works great under Windows 95.

I rem out all Playsound statements ....It runs a little bit better, but I am still getting the same error messages..

With Playsound out of the loop, it appears that forms opening and closing were also causing the same error. I fixed some of those with the :

frm.windowstate =1

It's a documented microsoft bug. I didn't have this prob on the Win95 pc. (250Mhz)

The machine in question is a Dell GX400, 1G processor, 500MB ram, windows 2000 service pack 2..

I still get the "memory cannot read" or "memory cannot write"..whenever any thing is displayed or a form is loaded or unloaded or text info from an array is displayed. Maybe I will try just frm.visible=true or false. It is very intermittant. I have done this on three Windows 2000 machines. Same result.



Thanks..

I was was making an API call to mcisendstring which was causing the problem. I was using the function load avi..Something in the way I was calling the video was not working properly under Win2000.
