Hi,
I am using the contextmenustrip in an application and add the items programmatically at runtime.
What I cant figure out is how to add a second level to the menu, like:
MenuItem 1
MenuItem 2 -> SubItem 1
MenuItem 3
Any help would be highly appriciated.

Though I can provide you the code but the best thing is you do it your self...
in the design time add the child menu as you like and see the code in the windows designer code area. the same way you have to add dynamically.. also you need the addhandler option with one procedure to add the handler for a dynamically added menu item

Any ideas how I can have the dropdown portion of a combobox to stay down after it has lost focus. I am tring to attach a tooltip but when my tip pops up the combobox looses focus and the drop down goes back up. I am using vb.net.

You could override the WndProc for the combo box and prevent the DropDownClosed message from being given to the ComboBox.

Hi,
I've seen people complain about this error other places, but noone ever answers them...
Can't find solution to this erro message:
'c:\documents....\...xls' could not be found. Check the selling blah blah blah
(it appears in excel when clicking the send to excel button)
It seems it's trying to open a file that doesn't exist yet or something...
Then I can click the button on my apsx page again, and it will work fine in excel...
But any help solving this problem will be very appreciated...
I'm sure some of you have seen this probelm before? :s

the code:
Response.Clear()
Response.Buffer = True
Response.AddHeader("Content-Disposition", "attachment;filename=Wells.xls")
Response.ContentType = "application/vnd.ms-excel"
Me.EnableViewState = False
Response.Charset = String.Empty
Dim myTextWriter As New System.IO.StringWriter()
Dim myHtmlTextWriter As New System.Web.UI.HtmlTextWriter(myTextWriter)
Exceldg.RenderControl(myHtmlTextWriter)
Response.Write(myTextWriter.ToString())
Response.End()
when i remove the line Response.AddHeader("Content-Disposition", "attachment;filename=Wells.xls")
it just opens the excel inside the browser without errors, so i'm guessing error is from that line for some unknown (to me) reason

Solved it myself, posting solution for others:
I had and needed this on top of my page
Response.CacheControl = "no-cache"
(Or it wouldn't show last added items..)
Had to remove that line to get the excel thing working...
And to solve the display thing, I just sent a unique new id for each time a record was added (open aaa.aspx?id="& newID &" instead of open aaa.aspx))

I don't want to sound harsh here, but why don't you learn how to use the APIs? - they are there to make life easier, and they will make your life easier when you learn them.

Ok, I am willing to learn but for this project would prefer not to use it, school is hectic at moment and haven't got that much time to learn. If it's not possible to achieve this task without API, could you recommend good place for API Newbies.

Not exactly sure what your problem is... is it throwing you an exception? Not giving you the correct data? What?

ia, workin in vb.net 2005 i need to add mp3 file that run automactialy when i run the aplication it run in background of application no mediaplayer for it how i do that
ma_refay

If you are using VB.NET 2005 you could start a BackgroundWorker and in the DoProcess Event you could have code to start playing the media file. Just include the BackGroundWorker in the Main method of the program.
|
|
|
|
|
Use API call : mciSendString to play the mp3 file

#define SCARD_ATTR_VALUE(Class, Tag)((((ULONG)(Class)) << 16) | ((ULONG)(Tag)))

This is a macro. You'll have to convert it to a function. << 16 is the same as * 2 ^ 16, or 65536. So a function that takes two numbers ( Class and Tag ) and return (Class * 65536) + Tag.

You need to handle the click event and set a flag so you know if it was clicked before, and respond accordingly
