Thanks for the reply!!
Is there any reason you can think of for why the complier does not put up a fuss when you add form tags or that the page seams to work when you put a blank form in frount of the other two?
Cheers:

I guess it's been left alone in case you have a valid reason for doing so. But anything that is in a form that you define will not work with ASP.NET, because ASP.NET relies on the form it creates being posted back.

I'm trying to move the mouse over a button with code but I can't.
I found this property "Control.MousePosition" but I can't do it.
Someone can help me?
Thanks

use the following API:
Public Declare Function SetCursorPos Lib "user32" Alias "SetCursorPos" (ByVal x As Long, ByVal y As Long) As Long
|

|

Thanks a lot, it works well!!

Also try setting the Cursor.Position property.

I would like to know if there is anyway to embed a thumbnail image inside an image file if the file doesn't alrealdy contain it's thumbnail. Most image files already have the embedded thumbnail so you can use Image.GetThumbnailImage Method, which in case of large files reduces the amount of time necessary to read the thumbnail, I would like to embed thumbnails for the images that don't contain it for (faster) future access.
Is there a way? Thanks!

Really? Not in any documentation that I've seen on any image file formats.
Image.GetThumbnailImage() returns the thumbnail image of the Image object, not the image in the Image file. If there is no thumbnail generated for it yet, it will read the Image file generate the thumbnail image at the requested size, save it into the Image object, then return that to the caller.
The next time you request the thumbnail image, the cached version in the Image object will be returned to the caller. When you save the Image object back to a file, the thumbnail is not written to the file with it.

Yes, you're right (well not quite, the msdn help for Image.GetThumbnailImage() says that it looks for an embedded thumbnail first... I guess), but I think I didn't put the right question. If you save a file(TIFF or JPEG) in Photoshop for example, the file is saved along with it's thumbnail (in the actual file, not as a thumbs.db or anything like that... there is a checkbox in the Photoshop Save dialog). I want to know if I can do that with a VB application. Maybe saving the graphics does just that, but I'm not sure (you just said that it doesn't so...).
I hope this makes more sense. I tried to get a thumbnail with DrawImage(...) and it takes about 3-7 seconds for a 4000x4000 TIFF image, while using GetThumbnailImage() takes only 0.4 seconds for the same image (the image was generated in Photoshop with the Thumbnail checkbox checked).
Hope I was explicit enough, thanks for the prompt answer.

The thumbnail is an extension to the JPEG format. I can't find ANY documentation that says the Image class can save that extension.
All you can do is try to get the thumbnail, then save the Image. Load into Photoshop and see if the thumbnail is there or not.

I have the following structure:
This is my object
Public Structure structTransoverride
Public Account_Name As String
Public PolicyNumber As String
Public TransCodeOrig As String
Public TransEffDate As String
Public Override_Action As String
Public Override_New_Renewal As String
Public Override_Transaction_Code As String
Public ModifiedDate As String
Public ModifiedUID As String
Public Plan_Year As String
Public RowNum As Integer
End Structure
I need to initialize it? And set the values in the below subroutine. How do I do this?

End Sub
Where do I instantiate or initialize the object and to I make it public?
I will need to do a XXXXX objTransoverride As new structTransoverride ?
I will have this in my dialog form?
'Form overrides dispose to clean up the component list.
Public Overloads Sub ShowDialog(ByRef objTransoverride As structTransoverride)
'
' Do All the work that you want to i.e. the one that you have written in the Load
'
'
MyBase.ShowDialog()

STOP SHOUTING! Or at least get your caps lock key fixed.

That is not enough information. I don't know what you mean by "open a file using arrays"? Do you mean you want to read the contents of a file into an array of some kind? Do you mean you have multiple files that you need to open and the filenames are stored in an array?

Hi,
Cane somebody help me ..
I've a dataset that has some updated rows and some new inserted rows. Could I use the single update method of data adapter to insert as well update my data ???
|
|
|
|
|
Im still new to vb.NET but I believe that calling the datasets update method will automatically call all required update/insert/delete sql commands to make the database match the changes you have made in the relevant table.

I have a web site Built with .net. I am geting complaints that the page is scrambles up on mac's I have data grids and such running on the site. HELP!!!!
|
|

One of the projects that has just gone live put a few weeks of the project plan aside for fixing up cross browser problems. We also bought a MacMini for testing purposes.
You need to find out what the problems are. A user report of "the page scrambles up on macs" is not sufficient. And you telling us that "I have data grids and such" is equally vague. You have to see how it "scrambles up" and create some html pages that show the error and an equivalent that shows the result you want. If you cannot see how to get from one to the other you can post a sample and say something like "this HTML works fine in IE but not on Opera, can you tell me where I'm going wrong?"
You can then apply that knowledge to your code. You may have to have lots of conditional statement in your web application to render things differently dependent on the browser it will be serving the page to.
Hopefully this will help you define your problem better so that you can receive the help you need.

The best approach is to create the app as a Windows Service. You can find articles on CP that describe creating services, and the NET help has a basic walkthrough as well.

For Windows Startup, this would be a Windows Service application.
For when a User Login occurs, you could run a normal application from the Registry Run key.

I am working on a touchscreen jukebox program like some of the more modern ones you may have seen in bars or pool halls. It's quite generic right now but I have been playing around with the ListView control to display an accurate representation of the current playlist. I have gotten it so that the user can DragDrop items (music files) in (*not "into" from an outside source..yet) the playlist to alter the order of the songs, i.e. move track 1 to track 3, thus resulting in track 2 becoming track 1 and track 3 becoming track 2. You get the picture. Actually it's quite like the playlist ListView in Windows Media player right now. In any cause, when the user moves the media up and/or down the list I am drawing a line on the ListView Control between the items that the chosen media is to be moved and thus inserted. I am using Graphics and Graphics.DrawLine and it works fine. However, I have to ListView.Refresh() everytime the line changes otherwise a whole bunch of lines will just continue to be drawn on the playlist ListView. It is in Detail Mode Behavior btw. This is all dandy when I have just a few items in the playlist but when I get around 30 or so when I drag an item to be moved the ListView Refreshing causes the control to flicker. Nothing major but annoying and unprofessional. How do I get this to quit? The Media Player for Windows does not flicker. Also on a side note, when the playlist becomes too big for the ListView the scrollbars take effect however on mine I get a horizontal one as well and do not want it. Do I have to resize the ListView when it reaches a certain number of items to accomodate the width of the vertical scrollbar or is there a way to tell the ListView control not to display the horizontal scrollbar at all? Any help, suggestions, or comments would be greatly appreciated.

Hi guys
my question is simple : Is there a way to dock the main window of an application on top of the screen. When it's dock, any other window maximized (even outside our application) would not be OVER or UNDER our main window? (as the Windows taskbar?)
It would work if we could SET Screen.workingArea() but it is readonly... Any ideas would be welcome... thx
============= --> our main window
