Shell run-time error 5, invalid procedure call or argument

[dennijr]

ok, shell always used to be easy for me, now its starting to get annoying cause i dont know wats wrong

heres the simplist code possible:

Private Sub IExplorer_Click()
a = Shell("C:\Program Files\Internet Explorer\Iexplore.exe http://www.google.ca", vbMaximizedFocus)
End Sub

i have a program thats been on my desktop for about a month now that uses these 3 lines of code(supposed to be 3 lines but it doesnt quite fit) and its been working perfectly up till today. I attempted to run it, then when it got to this part, it highlighted

a = Shell("C:\Program Files\Internet Explorer\Iexplore.exe http://www.google.ca", vbMaximizedFocus)

and a messagebox appeared saying run-time error 5, invalid procedure call or argument. I tried making an even simpler program that just opened notepad during form_load, but it still didnt work, same error. It doesnt make any sence, all that stuff used to work perfectly.

Hi,
I think this is because of the second argument, "vbmaximizedfoc us" maybe you don have the constants set, why dont you try using the constan's value instead, something like

a = Shell("C:\Progr am Files\Internet Explorer\Iexplo re.exe http://www.google.ca", 3)

hope that helps

That would produce a compile error, not runtime.

I thought somebody was saying recently that Shell couldn't handle a path with spaces in it. Perhaps ShellExecute is better. Have a look at this thread.

I sometime meet this type of error. (Worked-code goes fault). I tried resolving problem and found the reason: missing one or more library in preference.
On the Project menu, choose Preference. One dialoge appears show all preferences of your project. If you see atleast one line have "...Missing...l ibrary...", so it is the fault.
If this library doesnot need for project, so simply un-check the library and click OK. If this really need, you can see the path to the ".dll" file. If the file is missing, u need copy one file to that location, or maybe install some other soft-wares that provide this "dll" file.

Are you sure you don't mean reference?

I've heard that too, and I also tried ShellExecute cause of it, but it still wasn't working, and besides, it doesn't make any sense that Shell can't handle spaces cause it was working before ...

Ok, I tried that, but I didn't find anything saying missing library, and there's only 4 things checked, so as of now, I'm gonna try searching on Google for the dll file that shell uses, if I can't find anything that way, then I'll just select all the references and test if it works, if it doesn't, then I'm stuck again, if it does work, then I have to find out which one it is lmao...

EDIT: kk, in system32, theres shell32, shell, shell manager, shell style and shellvRTF. Shell manager and shell32 are the only ones that VB6 will add a reference to, and if I add them and select them, I still get the same error,
any other ideas?
PS. ty to all people trying to help, it's greatly apreciated

Hi, I dont know how much this helps, but if in the worst case you get stuck, use an object with an internet explorer application in it.
check this out:

VB Forum - On Click

It might be an alternative.

well, it does work for internet explorer, but i dont know how to make it work for other programs aswell...

ty

i can use this in the meantime, BUT, i would still like to figure out why i cant use shell anymore

i didnt use shell execute from that link, but i did finally find annother source, which had what i needed on it, and i can change it for more than one program

but...

i still wanna no why my shell doesnt work anymore .... and its not cause of spaces in the title, cause i get the same error even with files that dont have spaces

I'd be really curious to know what went wrong, too. I finally got around to trying your original example, and of course it works. So for some reason your system simply became unable to fire off another process. Could this have been some security measure you weren't aware had been implemented?

Another thought which occurs - if, say, you had something which was being displayed "system modally", then maybe trying to start up anything with the focus causes that error. Could you go back and try the original version again to ensure the problem is still there, then try it without giving it the focus?

That's about it - I'm all guessed out.

For the second part, I thought about that too at one point where I was trying to do everything I could think of to get it to work, I made it as basic as it could possibly be.

For the first part though, that could be what it is, that somehow my security isn’t allowing shell to connect any more, but I haven’t changed anything security-wise recently.

There were 2 things that I did in between when it was and wasn’t working (not including things I do all the time, like msn messenger etc).

One of which was downloading a transparent picturebox user control for use with another program in VB6 (which works amazingly well) and at the time I wasn’t quite sure how to get the user control to work as I had never used it before, so I attempted to put it into system32, and later removed it of course. The second thing I did was download a program made in C++ coding.

Could the user control for VB6 cause an error, even without the trans picbox user control in the program? I know the C++ program is safe, but it does connect to the internet to receive updates, could something inside the program have stoped shell from working by some sort of conflict?

could either of these (or maybe still something else) be causing an error?

Thanks again for trying to help.

Hi Guys,

i have a similar kind of problem which i faced while developing Excel VBA Macro.

i have two lines of code in different modules in the same project

1. RetVal = Shell(FILE_PATH & "EXTRACT.BA T")

2. RetVal = Shell(FILE_PATH & "EXTRACT.BA T")


Then 1st shell command works fine. and i did not get any error.

but when i tried to execute the 2nd module which contains the same shell method as in (2), i am getting the error "Invalid Procedure call or argument", Runtime Error 5.

and it also works well when i say "var = Shell("calc.exe ")

i am very much confused with the behaviour.

Please anyone in this world can help this.

Thanks

I started having the same problem with Shell. To begin with all shell's in my program worked, then a few stopped working, there were no changes to my system. Then more and more of them quit working.

My development system is Vista with UAC on, but it has been for over a year before they shell started to crap out. I also did not download any new service packs/ updates to Vista before Shell quit working.

Right now there are still some Shells that work IE

Retval=Shell("n otepad.exe",Vbn ormalfocus)... works right now
Retval = shell(Mypath$ & "my program.exe") ... worked until yesterday
Retval = shell(Mypath$ & "my other program.exe") ... worked until a month ago
Retval = shell(Mypath$ & "my other other program.exe") ... worked until a 2 months ago

I have searched the net trying to find out why but no joy. I believe it has something to do with Vista UAC. Anyway my solution is to use API with:

ShellExecute Me.hWnd, vbNullString, Mypath$ + "My Prog.exe", vbNullString, vbNullString, 1

It seems to be working now... who knows if it will tomorrow??
