Hi,
I am running vs 2003 and uploading a user defined excel sheet into an asp.net web form (vb.net code). The sheet consists of 21 records with about 50 columns. The problem is that I have the datagrid on a DIV tag for scrolling. But when you scroll it is painfully slow. Can someone suggest how I can do this so it won't be slow. Thanks.

A DIV tag tell's me this is an ASP.NET app. You have no control over the scrolling speed of the web browser. ASP.NET code runs exclusively on the server-side, generating HTML for the client. It's up to the client how to render the page image.

Yes it is an asp.net app with vb backend. So there is no way to make this run faster on a machine something. It is an internal application that is running terribly slow on every machine that I have tried including mine.

No. There is nothing you can do in your code to speed the scrolling up. Once the browser has the page, that's it, your ASP.NET code is no longer running.
You said it was 50 columns wide?? Try providing another method of narrowing that down. If there's one thing I hate about web pages, it's scrolling side-to-side to read information on it.

I have created two files using .Net Setup wizard and they are:
1.)Setup.exe
2.)MyProject.exe
Now which one of these two i should double click to install my .exe file.
|
|
|
|
|
The Setup.EXE will also come with an .MSI file. Both files must be in the same directory for the installation to work. All you do is double-click the Setup.EXE to launch the install.

Thanks
Thanks

do you really need a .tlb file? you can put a com wrapper on the dll(class library) and then in vb6 you can do a createobject to it?
|
|
|
|
|
Could you please tell me how i can do that!
Thanks

You're pretty much wasting your time using a StreamReader, of any other file operation. Office files, prior to Office 12, used a multiple-stream format that was very difficult to decode manually. Your only hope is to use Automation to start an Excel instance, have it load the XLS file, then you can use the automation interface to get that scripts you want.
No, I don't have any examples.

This is a common issue. The issue is, you need to learn to program more basic stuff before you can write games. As you said:

That's because you're trying to do the hard stuff before you have a grounding that will enable you to do it.

Hi,
how to set a property only of "desegn time" (hiding it at run time) in VB6?
Thanks.
|
|
|
|
|
Something like this:
Const m_nAmount As Long = 32
Public Property Get Amount() As Long
Amount = m_nAmount
End Property
Note that Let accessor is not defined.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

The solution is OK, the problem is wrong! 
If you are the developer of the COM library, then you've the power to make the property read-only. On the other hand, if you're the client of it, simply access the property only for reading, finally, if you are ? then, my friend, I don't known.

Then I explain myself better… I must have the property to set at design-time in the VB property page (uc of OCX), but in "side client code"(OCX) i must HIDE this property. If I do not define the property "let", it's not visible in the VB property...

There is no way to hide the property at runtime. If I remember correctly, there is no property in the VB6 runtime to tell the component it's in Design mode or Runtime mode.
You cannot change the visibility of the property. It needs to be public for the designer to work on the component and the user gets to set it's property. You cannot change that visibility at compile time.

You can put this line in your property and during design it will allow any change and during runtime it will raise an error "or you can use a messagebox too" or just ignore the change:
Public Property Let EnableCheckMarkColumn(bVal As Boolean)
If Ambient.UserMode Then Err.Raise 382 '<--- won't let a change happen at runtime
mbEnableCheckMarkColumn = bVal
PropertyChanged "EnableCheckMarkColumn"
End Property
|
|
|
|
|
I forgot about Ambient! :-> Can you tell it's been 6 years since I've touched VB6??
Anyway...you're right. You can check for the run more, but you still can't change the visibility and hide it, like the OP wanted. Something he'll just have to live with...
