MS Sample Code Master Drop

[Jean Dophin]

I am using vs2003 and visio 2003 sdk. I created a new project from the
wizard. Then I copied and pasted the master drop code sample to the
generated code. Anyway, it compiled fine, but it does not show anything on
the screen. Even when I disabled all the macros. Even the message box does
not show. I don't know why, any suggestion? see the code below

I am using vs2003 and visio 2003 sdk. I created a new project from the
wizard. Then I copied and pasted the master drop code sample to the
generated code. Anyway, it compiled fine, but it does not show anything on
the screen. Even when I disabled all the macros. Even the message box does

It seems that your problem is completely unrelated to dropping a
master.
Try creating new project from scratch (using wizard).
Run this new project. Does it show the message the box now?

If not, maybe you have disabled all add-ins events in visio? You can
check the value of this setting in visio options (it is NOT macro
setting, it is add-in's setting). Also, maybe your add-in (or rather
mscoree.dll) was placed by visio to "Disabled items". Try clearing
this list.

Kind regards.

 

[Jean Dophin]

What you said probably true, since I did not see the message box. Since I am
not in that computer today, I will try your suggestion on moday.

Thank you

 

[Jean Dophin]

I tried your suggestion, but it did not work. I am using visio 2003 and set
the security level to the lowest. I couldn't find the disable list, but I
went to tools->macro and saw a list. I don't know if this is the one you are
talking about. When I created an .exe applicaiton, I can see the dialog when
I ran it. But, when I created a com application, even when I checked allow
visio to load the add in when visio is loaded, I still don't see the message
box. I event set a breakpoint on it, still did not see. Maybe something
wrong; any suggestion?

I tried your suggestion, but it did not work. I am using visio 2003 and set
the security level to the lowest. I couldn't find the disable list,

The Disabled Items list can be found at menu
Help -> About and look for the button at the bottom.

 

[Jean Dophin]

When I disabled it, visio came and quickly exit abruptly. I don't know why.
I will continue troubleshoot; maybe something wrong somewhere.

 

[Jean Dophin]

Right now, when I disable the option from the help menu, then visio just quit
after opening. Then when I ran the program back, it came up with a dialog
box says:

"visio experienced a seriosu error ...... would you like to disable this add
in ... ti reactuvate this add in click about .... yes/no"

basically it, I think something maybe wrong with the mscoree.dll

i a using vs 2003 sp1

 

[Paul Herber]

er, what have you disabled ?

When I disabled it, visio came and quickly exit abruptly. I don't know why.
I will continue troubleshoot; maybe something wrong somewhere.
