I have this flexgrid which shows a different tooltip for every cell it contains. Now I would like to see this exact same tooltip for every cell when I put the flexgrid on enabled = false but I can't find a way to do this.
View 4 RepliesI want to do is make a notification system, kind of like aim were a new little box will show up to alert the user of a couple different things.
This is how far i have gotten :
Dim popups As ArrayList
Public Sub newEvent(ByVal title As String, ByVal description As String)
popups.Add(New Form())
[CODE].........
I use an arraylist because i dont know how many messages will come around the same time, but i could switch to an array if i must. this is the form that i made as kind of a template :

Its just got a couple text boxes for now. how can i make these new forms every time i have a new message to display and the clean up after them when they are done.
Currently have created/extended the DomainUpDown class hoping I would be able to add one simple feature: I was hoping to be able to show a tooltip when the user mouses over the control that would show the next and previous item in the list. However the DomainUpDown class does not have a mouseenter event and overriding the mouseenter method does not seem functional. Is there something I am missing or do I just need to create my own MouseEnter event?

I m providing minimize to system tray feature in my application. For that I used Noticifation Icon. I used the followed snippet to show the Notification Icon Tooltip for 5 sec
Call NotificationIcon1.ShowBalloonTip(5000)
Does anyone know if it's possible to skin the tooltip window so it looks like: Attachment 2448.Instead of the yellow box or the balloon like it does now?
View 1 Replieshow to show message in notification area like when a virus is detected or new message in messenger etc..
View 3 RepliesI want to display a balloon tooltip in the system tray. Currently, my app has four forms. the main form host the notifyicon. In process of operation with other forms, i want the current form to be hidden , and display a balloon message using the notifyicon of the main form.
in the form about to close this is what i did
c# Code:
frmMain frm2 = new frmMain();
frm2.ShowBallon("Logged in","Check for new mail....");
this.Close();
[Code].....
The problem is that the procedure executes, but dosen't show any balloon .Another problem is that the notify icon does not disapper automatically when the app exits, except you hover the mopuse over it.

I am trying to make a little class to show the balloon tooltip at the moment I got eveything I want working but have no idea how to set the forecolor of text and backcolor.
here the code I am using to show the tip, I added backcolor and forecolor but nothing seems to happen, I am also using Visual Express 2010 if that makes any difference.
vbnet
Public Sub ShowTip(ByVal obj As Control)
Dim tp As New ToolTip()

I'm aware that the tooltip object can contain an image. I am unable to make an image popup when the mouse hovers over a datagridview cell, since it is not possible to attach a tooltip object to a cell ( myTip.SetToolTip(gridCell, "Hello") generates a compile error)

I am trying to trigger a tool tip when a user enters a cell in a DataGridView and starts editing it.

The following below does note seem to be working.

I have a small application in which I need to show alerts if a particular condition is met. I have an mdi form and several child forms. Now the best way to show an alert is to show a tooltip on the right side corner of my mdi form. Though this works, but the problem is I want user to close the tooltip once he has read. Now the tooltip that vb.net provide does not support click events. If I give a long time duration the tooltip would be open all the time and if I give a short duration then it will close quickly. What can I do ?

I am using a Balloon tooltip to show the user which characters are invalid as a filename. I use the IO.Path.GetInvalidFileNameChars array and convert each character to a string, before appending it to a "Invalid filename characters:" string.
vb.net
If IO.Path.GetInvalidFileNameChars.Contains(e.KeyChar) Then
e.Handled = True
Dim str As String = "The following characters are invalid filename characters:" & nl
Dim invalidChars As New List(Of String)
For Each c As Char In IO.Path.GetInvalidFileNameChars
[Code] .....
The result is not pretty: How do I get rid of the 'non-visual' characters (they are probably newlines, backspaces, null chars, etc) so they don't clutter up the list?
showing MessageBox's from background workers.My program is a utility that has several functions and each function is boxed in a UserControl and then placed on a TabControl on the main form. A few of the utilities are batch functions that take quite a bit of time to complete their task. In order to allow the user to use the other utilities while a batch utility is running I make use of the BackgroundWorker class. It's quite handy!
My only problem is when I need the user to interact with the background thread, usually due to an error condition. I want to be able to halt the thread and display a MessageBox to the user. At first when you just do it from the background thread as demenstrated in the code below, it appears to work fine. But the MessageBox is not actually parented by the Form. If you select the Form, it will hide the MessageBox and the user thinks that the program has stalled. What's worse is that my program has a setting to allow the user to make the window TopMost, which means that the form will always hide the MessageBox when TopMost.
Option Strict Off
Public Class Form1
Private Sub chkTopMost_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chkTopMost.CheckedChanged
Me.TopMost = chkTopMost.Checked
[code]....
I have thought about passing the message using ReportProgress(), but the problem with this is that the BackgroundWorker will not halt it's opperation, and there is no built in mechanisim to send a message back to the BackgroundWorker.
How do I show the error icon and ToolTip when the user is editing the cell in dataGridView?
View 8 Replies[Code] This is run from inside a backgroundworker. It throws an error, Cross-thread operation not valid: Control 'pbUpload' accessed from a thread other than the thread it was created on. I have read and read and searched and basically come to the conclusion I am going to have to invoke the command but this is new area for me.
View 5 RepliesI am using tooltips to show information that overflows a label. The problem is that when the information is really long it spans the entire width of the screen and is difficult to read, Is there any way to limit the size of the tooltip?I was thinking one way may be to insert linefeeds at points beyond a certain width -- messy, but it would work.

View 1 Repliesi'm using two backgroundworker on two different invisible forms.One bgworker starts to work before the second, it depends on the cpu usage calculated every minute.

View 1 Repliesi have lurked on these forums before and finally signed up..i have a situation that, after days of searching the web, i have not been able to come up with a solution for.i have to fire off a function that takes a large amount of time (writes to database, creates files, etc etc)this function is a non-shared function of a class. if need be i could make it Shared.[code]the code works great, but what i need to be able to do is update a form with a progress bar as the job is processing.all of the examples i have seen that do this are being called from within a Windows Form and they access the form directly - i cant do that in this case. my form needs to be 1 form for 1 job being executed - can process multiple jobs at one time and thus i need multiple forms.i have tried making the form part of my delegate class but since it runs in the same thread the effect is it "freezes" until the job is complete.i have just started looking into using a background worker but again, all examples i have seen use the component as part of a form - that wont work for me.
View 3 RepliesI have a Worker.cs in a ZScreenLib DLL that does the following: 1. takes ZScreenGUI.cs (a Windows Form) as an argument 2. creates a Background Worker object and does everything 3. reports progress to the ZScreenGUI form via BackgroundWorker.ReportProgressThe user can create as many instances as possible of Worker.cs class and do the background worker tasks Now I need to create another Windows form called ZScreenCLI.cs and wish to make use of this Worker.cs class because ZScreenCLI and ZScreenGUI are pretty much the same but ZScreenCLI has much less features compared to ZScreenGUI. My question is, how do you manage to report progress to ZScreenCLI? The ReportProgress methods are tied with the controls in ZScreenGUI form. Obviously there is a problem with the concept I am using
