I do have the code set up to create an arry of the monotors. So I know what monitors are avaliable. Also, I do believe that this is possiable, and this is why: If I were to move a short cut to a nonprimary monitor and launch that shoutcut, the app will then be launch in that monitor.

Hi to ALL !
I need to develop a software in VB.NET that will monitor Telephone line, like i need to now the dialed number, time etc
Can any one give me some hints regarding this.
Thanks

You're going to need a new phone system to do this. There isn't a modem out there that will "monitor" the line and convert the dialing tones back to numbers.

Hi all,
I am using Datagrid in my application which has a bool checkbox column.
Sorting property is on for datagrid.
When datagrid is sorted, bool column behaves other way.
Like if i click on the first row of datagrid, it should change the status of firrst row bool column but it changes the status of any other row.
Why is it behaving like this?
Any Solutions?

what does your code look like to update the boolean column? most likely yuo're just using current row property of the datagrid, and you should be using the currency manager, to get at the currently selected row. just a thought.

Hi all,
I want to write a little function in VB.NET.
It must convert an array of byte ( ex: data as Byte() ) into other types like Integer, Float, Double...
I think the fastest way is copy memory like in C, but VB.NET does not support any such method.
Any help is appreciated, thank you.

Hi all,
I just found the method to convert to Integer types like Int16, Int32, Int64 by Marshal class: Use the Copy method to copy the data in Byte() into an IntPtr pointer, after that copy the pointer into an integer variable by the ReadInt32 method.
But the problem still exists: the Marshal class does not have any method to copy a pointer into a Single or Double variable.
Anyone have suggestion?

The .NET Framework has beaten you to this little project. Check out the BitConverter[^] class.

Thanks for your reply.
In fact, I want to develop a application which can play flash movie when the user click a hyperlink.
I have flash player. But I don't know whether I can call Pocket IE to run the flash player to play the movie.
Please give me some advices.
Thanks a lot!

I think all you would have to do is use the Process class to launch IE, giving the full path to the .SWF file as a command line argument. You can find the docs on Process.Start, along with some samples, here[^].

I have tried Process.Start. But it cannot be used in .NET Compact Framework. Any other choices?
Thanks!

Hello,
I am working on a case that would be so painful and time consuming if, there is no such way of doing what i need to do automatically. As you may very well know, applying the same action on a large number of images in photoshop and imageready is pretty easy, as well as it could be extremely tricky at times. Could VB.NET my saviour?
What i need to do is to open files from a number of directories which has the same basic subdirectory construct in which the image file is contained, embed a transparent copyright layer, and export the opened files to their original directories optimised, with a different filename. (The code could do it one at a time. Doesn't have to bulk edit the files.)
This process is something i normally do on a daily basis using my pre-recorded actions in Photoshop 7.0 but with one important difference: this time i don’t have the chance to bulk edit files because they all have the same filename and they are placed in different directories.
I think it would be much better if i give examples at this point:
What i have is a directory with several directories in it, categorized by consept names. In every category named directory there are several different directories with numbers in the end for various contents. The very last of this chain is a directory called XYZ. The image i have to edit is, in XYZ directory.
So the hierarchy would be like:
pictures>>cars>>car1>>XYZ>>image1.gif
pictures>>cars>>car2>>XYZ>>image1.gif
pictures>>cars>>car3>>XYZ>>image1.gif
So the image names are the same and they are located in the same directory hierarchy categorized by directory names.
What i need to execute is to open all the files i have to edit, make my edit then export them (save optimized as) in the same directory with a different filename such as image1D.gif.
Is there anyone to help me with a sample VB.NET code for this purpose? Or is there any kind of tutorial i could use for building image editing/processing applications in VB.NET?
Thank you.

Read my C# articles on image processing, but I think all you need to do is create a bitmap with your copyright message, and a magenta or limegreen background, draw it over your bitmap using a color key, then save them out. Quite a trivial exercise.

Have you tried copying the .TXT file to the SQL server first, then running this statement?

I am kindda lost, how do you copy .TXT to SQL server, somehow they gave this error
Server: Msg 4861, Level 16, State 1, Line 1
Could not bulk insert because file 'y:\pricefile\test1.txt' could not be opened. Operating system error code 3(The system cannot find the path specified.).

OK, suppose your SQL Server is installed on one machine. It recognizes the C: drive only on the machine it is residing on. It will not recognize the C: drive on a client machine. So trying to load a file with a path "C:\test1.txt" when the file is on the client will not work, because the SQL Server looks on it's own C: drive for the file and the file does not exist. If you need to run the action from a client, the SQL Server needs to recognize a mapped drive on the client. If you copy the file to the SQL Server machine, use C:\Test1.txt. If your file is on your local machine as C:\Test1.txt, AND your local C: drive is mapped to the SQL Server machine so it recognizes your local C: drive as "Y" then use Y:\Test1.txt.
Hope that makes sense?
