I know it seems silly. I was hoping to limit my coding.
This is what I am trying to do...

I have a combo box with (=, <, >, <>) operators in it and a piece of code that executes depending on the operator the user selects. Without the option to assign the operator a variable my coding become slightly longer with the use of a select statment that checks each possible option.

Thanks,

Unfortunately, that's what your going to have to do. Even if you were to make a class that did something like, internally, the class would have to check to see which operator was involved, then make the appropriate branch to do the comparison.

WinForms component parented as an MDI child in a Win32 app?

Blaiser29-Jun-04 4:33

29-Jun-04 4:33

We have a WinForms component in it's own assembly which is used in our .NET desktop app; the window is set by the app to be an MDI child in the app's MDI window.

The component can also be used by other .NET apps that set a ref to our library. Lastly, the component can also be used as a standalone window for apps do not wish an MDI child for its functions.

Is there any way to expose this .NET component so that a COM app (C++ or perhaps VB6) could use the component as an MDI child?

Thanks ... Blaiser

Well, it's too much to go into in the Forums. I'll say that is should have been a desgin consideration before you even started to code this. Yeah, it's going to be that messy... ThNick Parker put together a great little article[^] that describes what needs to be done, complete with examples.

Could not set the focus to a text object

Hello VB Gurus!

I have got a very little problem here. I got "an invalid procedure call or argument" when I inserted this code on on the Form_Load procedure:

txtDescription.SetFocus

With this, I could not have the text object, txtDescription, focused on form start-up.

Please check.

Thanks,

I think you can't set focus in form load because the UI of the form is not completed its setup yet. If you want a certain control to have focus on display, try setting it's tab index to the lowest value among controls on the form that can receive focus.

Blasier is right about the controls. You can't execute methods on the controls in the Form_Load event. You can either set the TabStop to 0 for that textbox or you could do the .SetFocus() method on Form_Activated. But, using the Activated event has it's drawbacks. If the user switches to another app, then back to yours, the Activated event will fire. Same thing if you .Show() or .ShowDialog() another form. The end result of this will be that the focus will alwyas return to the same control when the user goes back to your form.

The best method is to set the TabStop on that control to 0.

EnableVisualStyles Question

I got this code:

<br />
dim frm1 as new frmLogin<br />
dim frm2 as new frmMain<br />
sub main<br />
application.enablevisualstyles()<br />
frm1.showdialog()<br />
<br />
application.run(frm2)<br />
end sub<br />

It seems that the first form does not get the xp visual styles and the second form does. Is this a bug or is this expected? Can I ask why? Is there a work around? I need the first form to come before the second form so that I can configure the second form appropriately.

Re: EnableVisualStyles Question

Dave Kreskowiak29-Jun-04 2:50

That's because you have the Application.EnableVisualStyles() in the wrong place. It should go before the Application.Run() for your main form, not inside it. The proper place for it in the Main function of your code. Just use Edit/Search and you'll find it. Also, put an Application.DoEvents() between the .EnableVisualStyles and the .Run for your app:

Sub Main()
    Application.EnableVisualStyles()
    Application.DoEvents()
    Application.Run(new Form1())
End Sub

There is not native supprot for it in the .NET BCL. You'll have to download and use the Speech SDK 5.1, here[^], or wait until the Speech.NET SDK is available. In either case, both will come with sample code. Although the SDK 5.1 will not be VB.NET specific, it can still be converted to VB.NET and used.

By d way,may i know without Speech SDK 5.1,will i be able to develop text-to-speech and voice recognition program by using VB.NET?

From my research,i had get few sample program on text-to-speech.But when i try to develop same program,i found few component is not available like AxHTTSLib.Is it because i don't have d Speech SDK 5.1 software?

Thanks!!!!!;)

Not unless you want to develop your own Speech SDK from scratch. Good luck, you've got alot of research to do!

YES! You need the SDK in order to do this.

Provided any firewalls in the way have the proper holes punched in them (ports opened up), you don't need to do anything special. Just include the complete Internet address of the server in your connection string. I don't think you would really want to expose an SQL server to the VERY HOSTILE environment known as the Internet, though!
A sample connection string:

Initial Catalog=MNFPool;User ID=MNFPoolUser;Password=MNFPoolUser;Data Source=mySQLserver.whateverdomain.com;

or you could use an IP address as the Data Source:

Initial Catalog=MNFPool;User ID=MNFPoolUser;Password=MNFPoolUser;Data Source=53.200.154.20;

TO that end we've been using SQLXML / SOAP here - once you get your head around it, it's not too tricky to set up, but does have some limitations etc...

I take it your using VB6? This was a know issue that has nothing to to with the component registration. See this[^] Microsoft KB article for the fix.

Same thing applies. The license is for the design-time fix of the control, not VB6...

What are you trying to use the Comm Control for anyway. There's already .NET libraries that can handle serial and parallel I/O without resorting to ActiveX controls, such as this[^] article on CodeProject.

What do you call using an .OCX file? It's just somebody else's code, but in this case, it's really old school code.

I have to congratulate you on wanting to write your own class for Serial Comm. It's the best way to learn and to get all the features you want.

You can use a regular expression to validate the input. Also, if you use a regex and the input in invalid, it can return the closest match to the format that is needed. Say the user inputs 123.453.24265. The following regex will return a match with 123.45:

^([0-9]{1,}.[0-9]{0,2}){0,1}
