From what I understand, Christian was saying you don't have to use C#. The code to do the comparison happens to be in C#. You can call this from your VB.NET project.
Also, it is a bit finalistic to say "I don't use C#". On a day-to-day basis I don't use VB.NET, but since there are over 45000 similarities between VB.NET and C# and only a few dozen differences it is easy to pick up one if you know the other.

No, there isn't anything in the .NET Framework pre-written for you to do this.
The code to compare two images has to be written in C# is you want the speed. The reason for this is because C# supports pointers in unsafe code blocks while VB.NET doesn't support pointer at all. You can write the library to do image comparisons in C#, then use the resulting .DLL in your VB.NET project.

If the game uses DirectX, no there isn't. The game isn't rendered in the same frame buffer as the Windows Desktop. Your window WILL be on top of all other windows, but will still not be visible at all under the DirectX render window, if running in full-screen.

What the other guys said, plus, what you wrote above is the only way in VB.NET, and it's slow.

This means one of two things:
1 - I can't work out how to use google
2 - I'm asking for help in stealing software
If 1, it's pretty simple. If 2, we're not going to help you. SQL Express is free, and easy to find online. SS2005 is not free, and you need to buy it.

Hi,
I am working with a project where there is a need of report generation.
I had developed the report in crystal reports.
All the data is view properly but the only problem is images.
Images i am accepting the data through richtextbox.rtf into the data base and displaying the data back to crystal report using the data object with setting the property o display rtf data.
But it only loads the text data from the database but not the images between the text.
Any help would be great...
Thankx
Jats

You might want to ask this question with BusinessObjects support. I don't know if CrystalReports supports inline images in RTF fields.
[EDIT]
Well, my Google-Fu has failed me but briefly. CrystalReports doesn't support any image tags in RTF data. You can find more on it here[^].

This is the code:
1.Dim mm As ArrayList = New ArrayList
2.Dim i As Integer
3. For i = 0 To intTotParam - 1
mm.Add(arrInputFileData(arrPosition(i)))
Next
4. Dim ss As String() = mm.Item(0)
5. MessageBox.Show(ss(0))
I am getting the error "Specified cast is not valid" at line 4.
Actually i need to sort the arraylist and find the largest element.
Retrieving the strings that has been added in the arraylists is of primary importance in my project and needed at many places.
Please help me out

You can't convert an object to a string just like that.
Try converting it to string format first.

can you give me the code
for converting the object to string format
and displaying in message box
|
|

This is why arraylist totally sucks. You can't use VB.NET 2.0 ?
object has a ToString() method, that's the best way to convert to string.

I tried the following
Dim ob as object
for each ob in tempArray
dim m as string
m=ob
next
if ob had ToString Method it should have shown...but it only has to
GetType method.
Seems there is no way to retrieve strings from the arraylists
|
|
|
|
|
Try Cstr(ob)

EVERYTHING in .NET has a ToString() method. It's guarenteed.

Rubbish. If it's a string, you can cast it to string. The issue is, the ArrayList is nasty, it stores objects, ToString would not crash, no matter what the object is.

It doesn't work because you tried to convert an object (you didn't say what was stored in arrPosition()), stored in element 0, to an Array of Strings as specified by your String() declaration.
I believe it should have been:
Dim ss As String = mm.Item(0).ToString()

Thanks in advance, Zaegra

You need a nested loop to compare the x and y directions. You need to post your code for us to understand where you're failing in what is a pretty straightforward task.

I have encorporated Window media Player in my Vb.net Project. I am getting the different different Urls and want to play through my media player. But I am not able to play these Urls through media player.Please help me .
I am storing the url in string like str
and then giving the command
windowmedia1.url=str
but it is not playing anything

I don't use MediaPlayer at all, but it would appear that you have to set the URL property, then call the Play method of the CtrlControls collection.
myPlayer.URL = "some URL..."
myPlayer.Ctlcontrols.play()

Guys,
Does anyone here can help me to create a utility program in vb6 that will prevent certain exe program from running? Can anyone give me code snippets.
Thanks!

That's physically not possible. How would you hope it would work ? If it were possible, VB6 isn't going to do it.
