Thank you! I'll take a look on both.

Hello Friends,
I develop in VB.NET and my Applications store data primarily in .accdb files, connected via Data.OleDb objects and using ACE provider.

Usually, but not always. For instance, if I manually click the Form and reactivate it, but my program is still interacting with WebBrowser content and gets it to navigate again (for instance,...

Hello friends,
My application has a single Form. It always shows in full dock one of a set of several UserControls. They alternate as user demands different functions from the application, so that...

Well, no special reason but my practice of always using TryCast whenever I'm not 100% sure of object's type, so I can test whether the cast succeeded or not without throwing an exception. Which I...

Dear friends, I need your help with solving this puzzle.
I wanted to wrap Word and Outlook interop code in classes that work regardless of Office Version on target user machines.
For that reason,...

Then, again, if there is a way of referencing Office Interop classes early that would allow my application to run seamlessy regardless of the Office version in user's computer (at least from version...

I don't think you need COM automation to accomplish this.
Two .NET classes can do all the job for you.
Take a look on System.IO.File -...

Dear friends,
My application already automates Word, Excel and Outlook.
Since its users can have Office 2007 to 2013 in their machines, i decided to stick with late binding to avoid compatibility...

Lots of Thanks! I'm still developing these interactions and the functions you've mentioned could come in handy, I'll take a closer look on the documentation for each one of them.
In my case, in...

Dear friends,
I need to fill a "File Open" dialog box with a string (file path and name).
Since my language has plenty of characters on the extended ASCII - for instance, a file can be named...

Is there a way to assure that a Timer and an OleDbConnection share the same thread? Might this SynchronizingObject property be used for that?
-
Thanks, my class had already two constructors, and the one without parameters was quite an idle one. Removing it solved the problem. The parametrized constructor retrieves previous settings and, from...

My project has a "Dialog" Form.
Its purpose is to allow user to select none, some or all itens among the content of a default array.
This default array with all possible choices must be dynamically...

Then, again, it was my fault not to see that everything that goes down must come up, and both keyboard keys and mouse buttons must have a pair of press and release messages in order to simulate the...

Yes, I'll try and learn to do that, for you've helped me before and I trust your advice. And Pinvoke.net sure is the place to go first. But...

Thanks. Let me explain my problem, maybe it helps more.
I have this DialogBox, it works for me as a generic list selector for large lists of items (it has two listboxes side by side and buttons like...

This may be a silly question, but if I can send an Integer value into a sub/function whose parameter is typed Object, why can't I send an Integer() array into a sub/function whose parameter is typed...

Thank you very much, that suggestion is nice, and in time, I'll implement it.

My application automatically performs the repetitive filling of some boring, hideously detailed, annoying forms in my organization's intranet, since they won't give in on collecting our branch data...

Thanks, .paul, that is exactly what I was looking for.

I'd like to share an interesting result of some simple modifications to Kleinma's brilliant original. This is what I did:
1) I increased tmrPopCheck.Interval from 100 to 1000;
2) I suppressed the...

I am not so sure about how to do so...
What I can say, in order to clarify, is this: my data source is an Access 12 file (.accdb), and all the OleDb commands I use to handle it are encapsulated in...
