Yes. Use the Tooltip control.
Add it to the form.
Then to add the tooltip:
myTooltip.SetToolTip(MyControl,"This is the text")
where myTooltip is the tooltip you created above and myControl the one you want the message associated with. If you look in the doc you can also specify the timing.

Yes, I know. But this tooltip will show when user stops the cursor over the control.
I want to show it with no action from the user.
Thanks anyway

You really have to read the documentation for the Tooltip[^] class. There are properties that let you control how fast the Tooltip shows up (by default, a half second), how long it stays displayed, and others.

But that I want is to show the tooltip without the cursor.
Maybe I'm not explaining well...
I'm reading the link you share and in one of the first lines says
"The ToolTip class allows you to provide help to users when they place the mouse cursor over a control."
I think that this explanation answer my question. It's not posible to show the tooltip if the cursor don't moves over him.

Nope. That's not the defined behavior of the ToolTip component. If you want Tooltips showing over all of your controls without the mouse being anywhere near them, you'll have to draw the ToolTips yourself. This is not a good idea though. You'll end up cluttering your user interface with all kinds of information that the user doesn't need when they become familiar with your app.
Think of if this way. Have you ever seen a Windows application that does this? Why not? Because the user interface was (hopefully!) well thought out to begin with. It should be intuitive to use without all the help showing on every control.
If you want to show a little help with whatever control the mouse passes over, other applications tend to put a short message in the status bar of the application window describing the functionality of that control.
The Windows user experience should be consistant acrossed all, or most, of the applications the user runs. If you deviate from the accepted, and more importantly defined norm's in the Windows User Interface Design Guide, you'll end up confusing the user more than you think you're helping them.

I am in the process of moving my pages from asp to aspx and I ran into a snag. I have an order form that I use to place items into a Yahoo shopping cart. To do this, I have 2 forms on the old asp page each having an item. When I moved this code over to the aspx page, I found that the first form just posts back to the aspx page but the second works fine. More over, when I put a blank form before the two original forms they both work fine. It seems only the first form does not work. This is a workaround for the problem but I would like to know what is going on. Please let me know!
Regards:
For example:
<body>
<form
id="Form2"
method="post"
runat="server"
>
--- This Form Posts Back to the aspx page
<form
method=post
Id=frm02
Action="http://order.store.yahoo.com/cgi-bin/wg-order?mysite"
>
<input
Name=vwcatalog
Type="hidden"
Value=mysite
>
<input
Name=vwitem
Type="hidden"
Value=item1
>
<input
Name=vwquantity
Type="hidden"
Value=0
>
<input
Class="submitbutton"
Value="submit"
Type="image"
src="http://mysite.org/images/CmdButton-AddMeToThisEvent-2F8DBE.gif"
id="btn1"
width="190"
>
</form>
----This form works fine ---
<form
method=post
Id=frm03
Action="http://order.store.yahoo.com/cgi-bin/wg-order?mysite"

ASP.NET works by creating it's own form, you need to rewrite this to not use two forms.

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:
Steve

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?

NOTE==> It cannot be declared in Sub highLightRow it since it will have to be passed in
the sub routine below called doModify()

objTransoverride.Account_Name = Convert.ToString(grd.Item(RowNum, 0))
Private Sub highLightRow(ByVal sender As Object, ByVal e As MouseEventArgs)

Me.SqlDataAdapter1.Update(Me.DsTransOverride1)
Me.DsTransOverride1.Tables(0).Clear()
Me.SqlDataAdapter1.Fill(Me.DsTransOverride1)
Me.DataGrid1.Refresh()
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()
End Sub

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.
