Re: How to communitcate to a port.

The .NET Framework 1.1 does not come with a Serial Port class. That showed up in .NET 2.0.

Google for "vb.net 2003 serial port class[^]". There's a smattering of custom written Serial Port classes out there, but each one is different in how you use it.

If you want to use a serial port in .NET I strongly advice you to switch to .NET 2.0;
you would need the FrameWork itself, then an IDE (Visual Studio Express Editions
are free); both can be downloaded and installed in the matter of say 2 hours.

After that, you read up on the SerialPort class (there are some nice articles on CP about it),
choose a port (say "COM2") and you can start debugging...

I already told you here[^]. Noone is just going to hand over the code to you. You have to write it yourself. When you get stuck with a problem with your code, then you asks specific questions about it.

To start, a little Google goes a long way. Results for "vb6 simulate mouse clicks[^]".

Nope. Will hand an invoice that he couldn't pay with the kind of money from his area. I wouldn't even accept their currency Poke tongue | ;-P

You were a "stand-up philosopher" in a previous life, weren't you? I like it! Laugh | :laugh:

Reasking a question in which you have already gotten the answer is bad. Telling people to hand over their code (even if you say please) is bad. Now go to the corner and read the forum guidelines.

Oh please, this is getting old. I'll hand him over code, but I will hand an invoice along with it. Roll eyes | :rolleyes:

opening a pdf with vb6

I have a button, and once clicked, want it to open (and display) a pdf document. How do I go about this? Thanks.

Dave Kreskowiak23-Jul-07 6:47

23-Jul-07 6:47

You'll need a 3rd party control to load and display the PDF. Visual Basic doesn't come with anything that can do it. Google for one here[^].

Thanks Dave. Any recommendations? (ie, have you used one ever?)

Nope. I haven't had to do anything with PDF's.

Actually I didn't need anything 'third party' All you have to do is:

Dim acroApp As New Acrobat.Acroapp
acroApp.Show

Dim acroDoc As New AcroAVDoc
acroDoc.Open "C:\filename.pdf", ""

thanks anyway though...finding freeware controls to open pdf sure was a pain, I'm glad "this" works!

When that works, why not simply use Process.Start(myPdfDocument) ? that works
just like double-clicking myPdfDocument in Windows Explorer.

The advantage is you now depend on the existence of a file association (for PDF)
instead of on a particular PDF reader.

Actually, this IS third party. Acrobat is not installed with Visual Basic. What you're using is the COM server that's installed with Adobe Acrobat Reader. Don't try and distribute your app to other machines without verifying that the same version of Acrobat Reader your machine has is installed on other machines that your app will run on.

I've used a Glyph & Cog product to work with PDFs. I used the XpdfPrint, which doesn't display PDFs, just prints them, but they have some viewer controls and they were very helpful when I called for advice and questions. The price was pretty reasonable too:
http://www.glyphandcog.com[^]

Also, I Adobe has an SDK...I couldn't get it to do what I wanted with printing, but perhaps you would be able to use it for viewing. You should be able to just google it or search their site. The up side of this one is that it is free, the downside is that the user will have to have adobe and you will have to code for each versin of adobe.

Another product I've used is the Studio Enterprise .Net toolset from Component One. They are a bit more pricey, and you have to buy the whole package even if you want just one component, but I had a lot of good help when I called with questions on this product as well:
http://www.componentone.com/StudioEnterprise/NETToolset.aspx[^]

Hope this helps.

Hello
I have tried different things for this, but it is not working yet. I have a web page project under construction. When button1 is clicked should pict1.jpg be shown in the imagebox1 and when button2 is clicked should pict2.jpg be shown in the imagebox1. Pictures are located at server. I can not get this working.
