Hello,
I have a VB dll which is invoked from VC client. VB dll is a COM component and it displays a form to input data.
The problem is that most of the times, whenever the user clicks the mouse outside the VB dialog, the from goes nehind the vc frame.
the VB form is loaded as modal still it happens.
Any suggestions.
Regards,
Deepti.

If you want it for the web, see your repeat post below and Chris's suggestion.
If it's for a Win32 client, consider using GDI+ and painting onto the form directly.
Cheers,
Simon

You mean in order to display it in a html page, i should save it as jpg.
If we go one step back, to making the graph it self.
How can I do that>?

2D bar graphs on an HTML page are easy...
1 - Create a table that has as columns rows as you need data columns.
2 - Create a gfew gif images that are 1 pixel high and as wide as you need the data column to be.
3 - Figure the biggest size you need to hold all your data and create your table to hold that size.
4 - Figure each of the other data points as a percentage of the highest value.
5 - Place each of the images into the table column, and set it's height equal to the percentage of that data point to the largest number.

I would like to clear few things for myself:

gif image is an object that i can choose,, is that correst?

Let's back up a bit here...
What type of application are you writing?
Web app or Forms based app?
VB6 or VB.NET?
|
|
|
|
|
The application is VB
it is a forms based.
and its VB6
I basically have two arrays , one for X-axis and one for y-axis.
and all I would like to make a bar graph.

Hi,
My VB application makes a graph, I need to save the graph as a HTML file.
How can I do that?????
Thanks

Well, if you want to save it as a HTML file, you probably want to use SVG. If you want to display it in a HTML page, save it as a jpg.

Hi

hi
You can have your HTML content in a variable name sTemp. The insert this code where you want to create the HTML page. Here sTargetFolder is the path where the HTML files resides and concat test.html to that path. Then print that sTemp variable then close. Now check your folder.
Open sTargetFolder & "test.html" For Output As #1
Print #1, sTemp
Close #1
Hope this will help.

The filesystem object lets you read a file a line at a time.

I'm writing a com callable wrapper to make it possible
for vb6 developers to call the new objects written in C#.
I have trouble to pass an array of any kind from vb6 to
the .Net object.
this is the method in c#:
public string TestMethod(string[] str)
and the call in vb6 is:
str2 = secAccess.TestMethod(str)
and then i get the following compiler error:
Function or interface marked as restricted, or the
function uses an Automation type not supported in Visual
Basic.
I also tried to use [MarshalAs(UnmanagedType.SafeArray)]
in the C# call but I get the same error.
Can somebody help me with this problem.
Please send an answer to mark.willems@rabobank.com
regards,
Mark

I figured out what the answer is.
To be compatible with COM you should pass the array By Ref instead of By Val(which is the default in .NET).

Good morning community,
Visual Basic reference widely shows how to create custom commandbar controls and how to handle events from them. One of the popular ways to do this for MS Office application is to assign the "OnAction" property for a created control. (e.g. cbCtrl.OnAction = "MyActionHandler") But how is this all implemented?
I am going to provide the same functionality for my CommandBarControl object. Firstly, I thought that Visual Basic queries for OnAction property and calls the function on its own, but I was wrong - my implementation of get_OnAction was never called.
Could you please tell me about how this OnAction functionality is implemented. Thanks.

I use a webbrowser contorl to navigate a page in my program. But when the page has frameset, only the first frame will be displayed in this control. So, how can I display pages with frames? Thank you.
|
|
|
|
|
Hmmm. I have have done this, but did not have any problems. Are you sure the HTML is correct? I also think that each frame is treated as a window, but dont take that to the bank. In other words, I am not sure I understand your problem. If you are trying to open an HTML file that has a tag in it the web browser control should just open it. You may want to make sure your web browser control is big enough to display all of the frames. I don't think I am helping much, but I hope it does.
