Check if control is really visible.

25-Jun-07 3:33

The code is easily convetible to VB.NET.

If you want a translation guide, all you have to do is look in the documentation on MSDN. Nearly every single code sample for any class, method, or property, comes written in VB.NET and C#. All you have to do is compare the two to learn the syntax.

Am using a tabcontrol for an app. 1 of these tab pages contains code which needs to be executed but not before that particular tab page is fully visible. Problem I'm facing now is that this code (which is in the Enter event of that tab page) is executed basically inbetween switching from tab1 to tab2. Is there a way to check if a tabpage or a particular control is really visible on screen?

It has a Visible property, is this not working as you'd hope ?

No, the Visible property already results to "True" even if the tabpage hasn't been complete finished displaying.

Why is that?

It sounds like it has something to do with the actual display of the tab page, and in that case it should be done in a Paint event. There might be other windows partly covering your window, so even if the tab page is visible, it might not be fully visible, and if you don't handle this in a Paint event, you don't know which parts are visible.

The 2nd tabpage contains some code which takes a bit of time. I want that tabpage displayed completely before that code starts. This tabpage contains information for the user of "how / what" is happening. There is no overlap of any other controls.
Let's say this tab page contains a label called "lblUserinfo" which contains a bit of informative text for the end user. I want the code not to start before that label is actually being displayed.

I don't like doing this, but have you tried sticking a Application.DoEvents() at the beginning of your "long running" code?

Normally, I'd be running all the code to setup the controls of every tab of a tabcontrol before I let the user see it. You treat all the tabs of a tabcontrol as a single control and not on a per-tab basis.

For instance, an options dialog with multiple tab pages gets and sets the values for all the controls on every tab page when the dialog is shown, NOT when each tab is shown. When the changes are done being made, the dialog writes all the values, on every tab page, back to persisted storgage and applies all the changes to running code when the dialog is dismissed. It doesn't do this when changing tab pages.

Controls are created prior to running the code. I'm just wondering if there is a way to actually check if a control is visible to the user. Just using control.visible() will result in True but that doesn't mean the user already sees the control.

No, there isn't.

Hey:

I want to pass two dimensional array in my function and return one dimensional array. My function will take two parameters:

1. two dimensional array
2. Row number.

Once I call this function, it should return me one dimensional array i.e the row.

For example,

Dim data(2,2) as Double<br />
Dim row as integer<br />
Dim tempRow(2) as Double<br />
<br />
row=0<br />
tempRow=returnRow(data,row)

When I called this function, it should return me the first row since row is 0

Can you please me how to pass the multidimensional array and return one-dimensional array back.

You can accept a multidimensional array like this.

Private Function GetRow(ByVal data(,) As Double, ByVal row As Integer) As Double()

End Function

The function also returns a 1-dimensnial array. All the function needs now is to get the values from the array and return them as 1-dimensional array.

MACRO Basic Programming?

Hi Guys,

Have a good day.

I am just new to VBA Macro programing in Excel. I hope you can give me a sample code on how to do it.

How will I code this one - dynamic worksheets with 3 columns inside each worksheets and I will display the content of all worksheets by creating another summary worksheet?

I hope you can send me a copy of your sample code in kind at hifiger2004@yahoo.com.

Thanks in advance and God Bless

Example: TestWorksheet.xls

CONTENT of WORKSHEET #1:

Column1 Column2 Column3
aaa 1 100.00
bbb 2 200.00
ccc 3 300.00
... etc.

CONTENT of WORKSHEET #2:

Column1 Column2 Column3
aaa 1 100.00
bbb 2 200.00
ccc 3 300.00
... etc.

CONTENT of WORKSHEET #3,#4,#5... and so on...

MACRO PROGRAM - When I click the button it will generate another worksheet with the content summary from Worksheet1, Worksheet2, Worsheet3..., etc.

CONTENT OF WORKSHEETSUMMARY:

Column1 Column2 Column3 Column4
Worksheet1 aaa 1 100.00
bbb 2 200.00
ccc 3 300.00
Worksheet2 aaa 1 100.00
bbb 2 200.00
ccc 3 300.00
Worksheet3 aaa 1 100.00
bbb 2 200.00
ccc 3 300.00
...etc.

The idea of this site is generally that you try to fix your problem and ask when you're stuck, not that you ask people to email you code.

It's also not common for people to ask VBA questions, you're welcome to do so, but I'd suspect there would be other sites more suited to VBA.

Hello Christian,

By the way, I would like to comment out by saying to me - asking people to email the code. As you read my email, this is my first time to do programming in macro. And as you can see concept is that complicated. The concept is there but the "How to do it" is a big question for me.

And you know Christ it is not that complicated, it is more easier than what I thought.

Anyway, nothing is personal.

Have a nice day Christian Smile | :)

Hi,
What I want is to list all the folders in another folder
ie GameFolder >
Folder 1
Folder 2
Folder 3

I don't know where on the users computer the GameFolder will be placed so I need the program to go and find it and then list all the names of the folders that are inside.

Hope I've explained this well enough to be understood.

Thanks
Graham

How to use FTP browser in Visual Basic.Net

24-Jun-07 6:45

You have a problem. Not only can the user change the name of the GameFolder, they can also change the name of it. So, what are you going to use to positively identify the REAL GameFolder?

Are you going to look for certain .EXE's or .DLL's?? Do these games write some consistent values to the registry, in consistant places?

You could look for folder names, starting at the root, but this can be a very time consuming process. You would normall start your search using the default names of folders on their default home paths, like under the Program Files folder.
