You can, the OWC object will generate a GIF image of the chart, you can do what you want with it. I have used it extensively in both Windows Forms and Web applications. If you get really stuck i'll knock you up a little example if you want.
Cheers

Thank you very much for your help, I just found the advertisment in this forum for free .net chart control. Here is it URL[^], but it offer only ASP.NET not VB.NET webform.

If it is possible, please provide me a small example (sample code) to work in VB.NET.

Hi All
I m currently writing a file comparison utility in VB.NET.
I'd nearly finished the damm thing, then I came across a major issue that's thrown a spanner in the works, and I may need to go back and re-write large parts of the comparison algorithm...
I think my solution is too simple and makes too many assumptions, I'm wondering if anyone has any ideas about how to go around this, or if anyone knows how current programs like WinDiff work?
thanks

Hi All,
I am trying to create a User Control with no BackgroundImage property, so that I override the property with Browsable is false as the followings:
<Browsable(False)> _
Public Overrides Property BackgroundImage() As Image
Get
End Get
Set(ByVal Value As Image)
End Set
End Property
Is it a correct way to do this?
Thanks in advance.

It can be done, but is overly complex for the benefit your getting. A better solution would be to code your own MessageBox control that exposes that kind of functionality.
|
|
|
|
|
Ok!Ok!
I've got a solution to your problem that although it is nasty, it perfectly works and is VERY simple.
Use the API Functions:
FindWindow to find the long handle to the MessageBox window.
FindWindowEx to find the handle of the button's window in the MessageBox window.
SetWindowText to set the text of the button using it's handle.
Doing so, just after calling the Msgbox function, will change the caption very easily, and the name change of the button cannot be seen at all!
I repeat again that although it is messy, it is simple, works perfectly and is a practice for API functions.

No. The T-SQL doesn't have any function that can do that.

No. The SQL Server has no rights to anything on the local machine and, therefore, no rights to execute anything on the local machine.

Do you want to create an application for e-mail or you want to do it some where in Outlook express or Microsoft Office Outlook? Please provide more clearly information.

The application sends an email using SMTP. The recipient is using Outlook.

I'm using the following code. I want to send a populated CrystalReport to a location as a PDF when the Totals button is clicked. When I keep what is between the *'s, nothing gets exported, there are no errors either. When I comment out what is between the *'s, the unpopulated .rpt file gets sent to the destination as a PDF.
Please Help!

Hi all
Does anyone know how to implement something along the lines of the "page preview" mode in word, in either vb6 or .net?
I have googled everywhere to no avail, other than finding highly expensive controls that are way too complicated for my purposes to justify the cost.
All I need is simple richtext editing facilities that the richtextbox already provides, but to display it in the "page" view that word can.
Thanks for your comments.

You'll either have to re-write the RichTextBox control yourself or go with a 3rd party control. The RichTextBox class doesn't support the kind of "page" view your talking about.
[EDIT]
I should have clarified that this will be a large undertaking. The RTB does a half way decent job of editing, but not with the margins and page break support your looking for. I don't even know where your going to begin. This is something where you'll have to try a couple ideas first to see what's going to work and what's not. Kind of Proof-Of-Concept testing...
You'll need to integrate the rendering of margins as specified by PrinterSettings. You'll also need to get the page size, convert all the measurements into display units, handle ALL control rendering, editing, RTF rendering, ...
Come to think about it, that's why the 3rd party controls are so expensive. Too much is invested in research and development making the very component you want.

Im not worried about the printersettings. Thats something I can already do. Im just scratching my head as to how you get a scrolling page view! lol. I've previously played with pictureboxes as containers etc, just wondered if there was a known avenue to pursue.

I am developping com addins for word.
I want to find out if there is a way to click
on the customized button in toolbar programmatically.
I tried to call like this in module.
Application.CommandBars("MYWORDTOOLBAR_NAME").FindControl("MYBUTTON").execute
but I am just getting this error message
"fail method "Execute" of object CommandBarButton"
Do you have any idea why?
