Hello !
I'm using VB.net 2013.
Also I'm using a Spreadsheet control form a third party tools.
I have a problem :
I copy data from an excel document , and Paste to spreadsheet control.
But before paste , I want to analyze the data being pasted.
The analyze that I want to make is :
If the data have been copied from Excel , I want to know how many cells contains each row.
If this number is greater than a specific number (x) , I want to paste only the first x cells and ignoring the others.
Thank you !

Good noon friends! Recently, i posted on how to make two images appear far away. Now, i used the earlier method i was using before. I have painted the form with ground and cloud picture which now has the look of cloud and ground but finding it difficult to paint the walls to form a complete 3d look. How to paint the walls please? Language am using is vb6

VB6 is no longer supported; it's dead. It is also no longer sold.
VB.NET is available for free.

I have vb.net but this must be done in vb6.0

You "could" write it in VB.NET and integrate it into you legacy VB6-code. You can fake some 3d-ness depending on how you draw.
..but if it "must" be VB6, then I'm simply sorry

Good morning friends!
I am working on animation and painted a form with some textures to have 3d style and is working fine. Then i tried to place two walking boys animation. This is the logic i want to use: the two boys will walk towards each other and the one the at the rear will appear far away and the one at the base will appear near to viewers. How can I achieve this? Please... I know i need some math and physics calculation but i tried but couldn't do it.
|
|
|
|
|
This is just about scaling the images to be small for far away, and large for near. Simple division and multiplication should do it.
|
|
|
|
|
Yep, i tried something of this nature but couldn't meet the requirement.
Dim YGap As Long
Dim XGap as Long
Dim setHeight As Integer 'set boy2 at the rear height
Dim curY as Long' get the boy2 current y position
then on form load, i added this
YGap=Me.Height
XGap=Me.Width
on timer tick, i added this
boy2.Top = boy2.Top + 100
curY=boy2.Top
If curY <= YGap/20 Then
setHeight = 900
boy2.Height = setHeight
End If
If curY <= YGap/15 Then
setHeight = 1200
boy2.Height = setHeight
End If
If curY <= YGap/10 Then
setHeight = 1400
boy2.Height = setHeight
End If
If curY <= YGap/5 Then
setHeight = 1800
boy2.Height = setHeight
End If
then, i added this to ensure boy2 returns to his starting once he gets to the Me.ScaleHeight
If boy2.Top >= Me.ScaleHeight Then
boy2.Top = Me.ScaleTop + 500
End if
but, not working fine. Please give any idea.

I have no idea what that is supposed to mean.
Part of your problem is that you are using absolute values in your calculations, rather than scale values based on percentage differences between the images, and maybe even the background. The issue is really a mathematical problem rather than a programming one.
Also please use <pre> tags round your code so it looks readable like:
If boy2.Top >= Me.ScaleHeight Then
boy2.Top = Me.ScaleTop + 500
End if

Ok thanks. Then, what is the best idea? And please, i just downloaded something of that nature but unable to get the flow of the codes because there are no comments to understand the flow.
The poster declared
<pre>Dim i,j As Integer
p(200,200)</pre>
and he went further to say
<pre>For i=1 To 200
For j=10 To 150
p(i,j) = 1
Next
Next
For i=20 To 100
For j=10 To 100
p(i,j) = 1
Next
Next</pre>
and so on...
What does this really mean? Please, any idea because am lost at the post and it was posted 2005 not sure if there will be any reply if i ask there.

Sorry I have no idea. But there are many articles around that deal with displaying 2d and 3d images, such as can be found by Google searching[^].

Ok, thanks. Really appreciate your effort.

I would say it is very unlikely, most of us moved on from VB more than YEARS ago and will no longer have expertise in a dead language.
You should not be putting your effort into a VB6 development but looking at rewriting the application using Visual Studio Express[^] which is FREE and includes VB.Net.
Never underestimate the power of human stupidity

Hi.. Am Trying disable taskmanager through button click in vb.net but it gives me error .
registry access is not allowed.
But i have logged in as ADMIN only.. 
Below is the code am using....
Dim systemRegistry As RegistryKey = Registry.CurrentUser.CreateSubKey(&quot;Software\Microsoft\Windows\CurrentVersion\Policies\System&quot;)
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
systemRegistry.SetValue(&quot;DisableTaskMgr&quot;, 1)
systemRegistry.Close()
End Sub

If you're getting "Access Denied", you're not running the code as an Administrator.
Since you're putting the value under CurrentUser, this will only disable Task Manager for the user running the code and not disable it for everyone who uses the machine.

I don't think that key exists in HKCU. Use regedit to check.

Under your Solution in your project name, (Click show all files button above your solution) there is a folder called my project, expand it and open the app.config. Change this line:
<requestedExecutionLevel level="asInvoker" uiAccess="false" /> to one of these:
<requestedExecutionLevel level="requireAdministrator" uiAccess="true" />
<requestedExecutionLevel level="highestAvailable" uiAccess="true" /> You can elevate your application to admin level by using the below code:
.NET
Dim RunAdminMode As ProcessStartInfo = New ProcessStartInfo()
RunAdminMode.UseShellExecute = True
RunAdminMode.WorkingDirectory = Environment.CurrentDirectory
RunAdminMode.FileName = Application.ExecutablePath
RunAdminMode.Verb = "runas"
Try
Dim p As Process = Process.Start(RunAdminMode)
Catch RunAsAdmin As Exception
Return
End Try
C#
ProcessStartInfo RunAdminMode = new ProcessStartInfo();
RunAdminMode.UseShellExecute = true;
RunAdminMode.WorkingDirectory = Environment.CurrentDirectory;
RunAdminMode.FileName = Application.ExecutablePath;
RunAdminMode.Verb = "runas";
try {
Process p = Process.Start(RunAdminMode);
} catch (Exception RunAsAdmin) {
return;
}
