Well, stupid me, i figured out why word commands weren't working, i had to reference them in tool/references.

Moral of the story: If you are doing vba from one ms app to another, just make sure you check and see if you there is a reference to it. Even if you might not need it, i would say its better to be safe than sorry

It is possible to run a script from the command line by typing script.vbs. Is it possible to pass parameters to that script? If so could somebody give me a short example of how to do it.

Thanks for any help you can give.

Hi
Try this first: "Wscript //?" (without the ")
Type it and you will get more information.
You can type it in the Start->run...
or from the command line .

Packaging and Deployment

I finally finished my application which compiles and runs perfectly on my computer, but zero luck with the Packaging and Deployment Wizard. Problem is I don't know where to begin to find out what is wrong. Here is what I know:

1. The "Wizard" says the build is good, generating a single CAB file.
2. When I try an install, "Setup" reports a "Runtime Error 216 @ 2F78"
3. Setup says the installation is successfull.
4. I try to run the newly installed software and get a "DAX Error - Library not Registered"
5. Next, "Runtime error 50003" is reported.
6. Program closes.

A few other strange things... It keeps trying to add Graph9.exe from the Microsoft Office Library to the build, even though I dont' use anything like that (seems to have something to do with the "Chart" component). I can elect not to include it, but it adds it to the cab file any way. The first time I ran the Wizard it said it could not determine if there are dependent files for Graph9.exe and comdlg32.dll. It no long comes up with that error. Also, the first time I tried it said that, if I wanted to run my application under Win 95/98, I would have to include DCOM98, but no instructions on doing so. It no longer does this either.

Bottom line, I am completely stuck. Is there some other tool for doing this (hopefully something more helpful). Lastly, I notice that when it does attempt the install, there is listing in the "Add / Remove Programs" utility in the Control Panel of the target machine. How is this done?

With a Cmd Button, I want to copy files (always the same (*.DAT)from C:\ to A:\.
But, the instruction 'CopyFiles "Source", "Destination" ' doesn't work.
How must I do ?
Thanks a lot ! Confused | :confused:

*.Dat is not a valid entry for copyfile... You must add a fileview control to your form. change its pattern to *.dat. Set it invisible. When you project runs set its path to "C:\" and use this code:
for i = 0 to file1.count-1
copyfile "c:\" & file1.list(i), "a:\" & file1.list(1)
next

have good programing,

Hi,

I would want to do the following from Visual Basic for Applications, in e.g. Word 2000/XP:

A macro that copies the current selection from the application (i.e. words), assigns the string to string variable, inserts another string in front of the previous and copies the whole thing to the clipboard.

How do I proceed? Thanks for any help.

What version of VB are you using? I have heard that using threads within VB6 is highly unstable and causes a lot of problems.

Here's a snippet from Dan Appleman, and the Desaware site:

Sigh... It seems that many readers missed my original point. The ideas was not to encourage VB programmers to use CreateThread with Visual Basic. It was to explain clearly and accurately why you shouldn't use CreateThread with Visual Basic.

So, when Visual Basic 6 turned out to be considerably less thread-safe than VB5, breaking the sample programs referenced by this article, what could I do? I suppose I could go back and revise the samples and try to make them work with VB6. But then the same problem might arise with later versions of Visual Basic as well. 

Visual Basic offers good support of multithreading including multithreaded clients in ActiveX servers (this is described quite thoroughly in the latest edition of my Developing COM/ActiveX components book). I strongly encourage you to stay within the rules defined by the Visual Basic documentation and not use the CreateThread API with Visual Basic.

For those who insist on pursuing CreateThread further, to start with you should eliminate all Declare statements and use a type library instead. I don't promise that this will fix the problem, but my initial testing indicates that it is a necessary first step.

If you want the entire article goto http://www.desaware.com/articles/threadingL3.htm, his articles are knowledgable, and he is also the guy who write Win32API for Visual Basic programemrs. Have a copy of that on my desk, err...wait, no, yeah, I'm a pure VC++ programmer =)

I used API createThread before in VB6 without any problem but I think my problem come from using an another many AvtiveX objects under the thread function and these objects need to initialize,but how these objects initialize in VB. best regards.

It doesn't matter -- if it worked before it's just because you were lucky. If you want to learn how to do threads correctly in VB go out and buy Matt Curland's new book

List Boxes

27-Jul-01 5:08

Hi everyone, i am newbie to Visual Basic. I have visual basic 6. My questions is that when a string is added to a listbox, how does the user see that information the next time the program is loaded.

I know that the info has to be saved into a text file which i know how to do but i don't know how to read the info from the file and display it into the listbox.

Thanks in advance !

Warm regards,
Sarah

During the form's Load() procedure you would Open the file for Input, Clear() the list box, then simply call Input # on the file to get a line and AddItem() to get it into the list, for each line.

If you're wondering how to know how many items there are, you should write out the number of strings (using the list box's ListCount property) to the file as the first line. Then, when you read it back in, the first thing you read is the number of lines remaining in the file to add to the list box...

Does that answer your question?

Re: List Boxes

7-May-02 18:49

hi,
try this

when you type a new string and submit write the new string into a file

dim F as long

f=Freefile 'to get a valid file pointer
'open and add string to existing file
open "c:\tmp.txt" for append as f
print #f,combo1.text
close f

on form load,

dim F as long
dim mStr as string

f=Freefile
open "c:\tmp.txt" for input as f
do while not eof(f)
line input #f, mStr
combo1.additem mstr
loop
close f
