I added a tooltip control in my form and set a tooltip for a checkbox. The tooltip shows fine until I check the checkbox... If I check the checkbox once and uncheck it, the tooltip never shows up when I hover the mouse over it... How to make the tooltip to show on mousehover no matter the checkbox is clicked or not?

View 1 RepliesI want to change default behaviour of tooltip and show it whenever a I need to. I have a registration form. When users leaves the current control, (when validating event is happenning more precisely) I validate the input text, if it's not valid then I set focus to the control again and I want then to show the tooltip, wether the mouse cursor is on the control or not.
View 5 RepliesI am working on implementing cell level error indication in my app and I have it set up to where it shows the error icon correctly and I tried using the datagridview FAQ sample code to show an errortooltip as well. I can watch as I set the errortooltip to have the proper data and display control (in mousemove event), yet the second I finish my mousemove event it fires the mouseleave event and resets my tooltip before the user ever has a chance to see it.
Here's my:
' show and hide the tooltip for error
Private Sub ChuteSinglesDataGridView_CellMouseMove(ByVal sender As Object, ByVal e As DataGridViewCellMouseEventArgs) Handles ChuteSinglesDataGridView.CellMouseMove
If cellInError.X = e.ColumnIndex AndAlso cellInError.Y = e.RowIndex Then
Dim cell As DataGridViewCell = ChuteSinglesDataGridView(e.ColumnIndex, e.RowIndex)

I have an unbound checkbox in my datagrid view along with other bound fields from a dataset. I do not need to send back the checkbox status to my dataset or the DB. Instead I will loop though the DGV and look for those checked and do another process with them after its done being loaded. The problem is this. When I check a checkbox, then check another, the first one goes back to unchecked and so forth, back and forth. There is no add, update or deletes needed for this DGV.

I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.

Have a unbound Datagridview with first column set as a checkbox and second column just has text.When adding a row the checkbox does not show, what am I doing wrong.Code to add Row:
DataGridView2.Rows.Add(False, FolderBrowserDialog1.SelectedPath)
The code that adds the rows also saves to a file and then there is seperate code to load datagridview at the start of the programme.If I close and reopen programme it displays the checkboxes.
I 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.

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 am working on a Data Survey Project and first I have a few questions about the different types of databases, and second, I need help querying my tables that have relationships.
1. I need a database that is stand alone. It is just the back end for the program. Simply to hold all the data an employee gets while out on a job. So would I be better using access, or SQL Express? I have played with both, but I do not want a large redistribution to my user machines. When I compile and produce this app does the SQL Database still work without installing any SQL Technology? Or do they have to go in after they install my app, and install Express?
2.Overview: I suppose depending on the first question regarding the database, it might change this question a bit, but none the less...I have 4 tables( using Access at the moment) I will be generating Reports based on data in the database. I haven't gotten that far yet. *Project* is the table that holds all the details that pertain to the job and client. It has a "one-to-many" relationship to *Survey*. So for one customer there are going to be many Survey Records. *Project Type* also has a 1-to-many back to *Projects*. Parts is kind of an orphan, but is linked to the *Survey* table with a one to many. So there can be many parts for one survey. I wanted this table for a drop down box, so the user could just simply select what hardware he was using instead of typing all the names and parts.
So in VS 2008 using the Designers and related Query tools, how do I constrain the Survey Data to one Customer? I have one form that opens from a button that is "New Project" and then there are all the *project* fields listed, so the user fills out the info and hits accept and that opens a new form called "frmSurvey" I need to add some code to the accept button to check what type of project is selected from the frmNewProject and then run a select query based on that. How do I write query statements in the code section of the form, without using the Visual Database tools?
Ill stop here, and get these questions out of the way first. If I could just get a handle on how to use the data properly with different forms and different controls with my queries, that would be great.

I have built an application where there is a MDI parent form and other forms which i have not declared as Child forms but have set these forms not to show in Taskbar. While the application is running, if i have any of these forms open and i switch over to any other application other than this and when i come back to it, all these forms hide. I cannot reopen it or see it anymore.. Why is this happening?? how can i sustain these forms as it is even when i leave the application.LuxCoder

View 6 RepliesI've just upgraded from Visual Basic 6 to Visual Basic 2008 Express Edition.
1. Show anothor form (ie. Form2)
2. Close Form1.
At present when I use the me.form1 , but both Form1 and Form2 both closes.I would like to press a button or on a timer, to show Form2, while closing Form1.
my scenario is this: I have two forms and a module. Let's call one of the forms MainForm and the other SecondForm. My module is running on a seperate thread to MainForm. A sub routine is triggered in the module, and I want it to display SecondForm.
I understand that I cannot do this directly because SecondForm needs to be called from the UI thread, which is shared by MainForm. How would I go about doing this? I'm guessing that I would have to use a combination of invocation and calls to MainForm to activate SecondForm.
Well I accidently double clicked both of my forms in a project and then they weren't pinned anymore so I exited them out hoping they'd be pinned aghain, but now when I open the project, no forms show up. Just blank blue wall... How can I get the forms back?
