View 2 RepliesI'd like to start by saying that simply though searching, DreamInCode has taught me alot about VB.NET. In fact, I would imagine without DIC as a resource, I probably wouldn't have been able to move forward and learn most of what I know now, just because I got stuck on some things here and there.Anyway, I searched around for information regarding how to "capture" a minimize event in VB.NET. I am working on the GUI for an application that I would like to have minimize to the system tray. Currently, instead of accomplishing this with the minimize function, I do it on the FormClosing event like this:
Private Sub MainFrm_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
'Cancel the attempt.
[code]....
That code works, and upon making the form visible again with Me.Visible = True the form is restored to its original position. However, prior to the form being hidden, the window manager draws a minimize and restore effect before eventually hiding it. Any change to the WindowState _after_ hiding the form does not appear to have any effect, so when the form is unhidden it is still minimized.is there a way to capture Minimize events, and when captured, is it possible to cancel them in a manner similar to what I did with the FormClosing event?

View 6 RepliesWindows forms Application. VB .NET 4.0 In my application I have a global boolean variable that keeps track of when changes are made and when they are saved called changesSaved. On closing even it checks the value of this variable before closing the window.. I am using textchanged event to automatically change the value of changesSaved to FALSE when text is changed.. Problem: The group box items are being populated dynamically so the user can edit the values or simply just view them. This dynamic population is causing the textchanged event to fire because the program is changing the text value of the box to put the values in that are stored in the database. The textchanged event should not fire unless the user him or herself enters a value or values in the text boxes..
Is there a way to specify the source i guess you could say for the text changed event or another way so that it will only fire when the user inputs information.??? Functions are as follows: The first is called by the load event to place the values in the box... The next one is the one that is being called as a result of the first one and is also the one that is causing the problems.

View 3 RepliesI'm writing a windows forms project in Visual Studio 2008 - VB, data are stored in SQL database.- I have a date field within Datagrid that could be Null or have a date in it. I had set it to show <none> when it's Null (Null is allowed for this field). The problem that I got is when user would need to delete the date from that date cell within the grid. I'm getting an error immediately after pressing "Delete" to clear the cell value. I had put in a work around - added the code for grid DataError event and assigned DBNull.Value to that cell and user is able to type in <none> for that cell or just press save, but it won't allow to go to the next cell in the grid if you don't save or type <none>. I'm sure that there is a better way handlig situation like that. May be using different event? I wasn't able to find anything else on it.- the other issue in the datagrid - if user fills in 3 cells out of 5 for example and press save while in the 3d cell - it won't save the value in the 3d cell. I also put a work around to check for the values in specific cells before saving but the problem with it - few cells could be Null (and should be Null). I can't check every single cell value and force user to type something in it.

we display a decimal(11.25) value in the grid . When we try to edit that cell its displaying only (11).Its not showing the decimal value when we try to edit that cell.
How to format that cell ?
I'm trying to parse a formatted percentage value back from a datagridviewcell that has been set with the "P" formatter:
double percent = 0.96
cell.value = percent.tostring("p")
gives me a displayed value of 96 % which is what I want.
Now what I'm looking for is something like what is provided for the other formatting strings - NumberStyles.HexNumber, Currency etc so that I can do this
double percent= double.parse( cell.value, NumberStyles.Percent )
which would give me a percent value of .96
I have scoured the .net documentation but can't find any sort of AllowPercent style like the others - is there one?
p.s. I see there is another question here like this and tried to expand on it in that thread, but was deleted by a moderator and told to post a new question.

View 4 RepliesI have this code in the onKeyDown event of the datagridview.
Private Sub DataGridView1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown
Select Case e.KeyCode[code]....
This works. When the Enter button is pressed, it acts as the TAB button.The problem I am having is this only works if the datagridviewer is selected.As soon as I enter data into a cell (A cell is selected) the code wont work as it is not set for the cell keyDown event. The event does not exist, so I have to somehow create it.
There are 2 non-modal windows displayed- 1]Form1 contains a Listbox with a list of forms 2]Form2 is the form which is selected in that list Form2 consists of a Maskedtextbox T1. In the Leave event of T1, the validation of text is done. If the data is invalid, a suitable Messagebox is displayed and Focus is set back to that Maskedtextbox (T1.Focus()).Now, if I enter any invalid data and click on the Listbox in Form1, the following things happen:
1]T1 Leave event is entered, focus being on the Listbox
2]Invalid data message box is displayed
3]Focus is set to T1(T1.Focus()) of Form2
4]After End of event, T1 Leave event is again entered. And now, Focus has changed back again to the Listbox.
5]Again Messagebox is displayed and T1.Focus() is done
The issue is, after step 3(focus set to T1), the focus is reset to the Listbox in Form1. Hence Leave event is entered twice and messagebox is displayed twice.
Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...
Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....
Presently, that will only display the data in column 0, row 0 in those labels...
Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.
I replace dynamically a label by a dropdownlist and a checkbox in a cell in a grid like this
[Code]...
The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
