Dim frmDisc As New frmDiscount
frmDisc.GET_SENDER(Me)
frmDisc.Show(Me)

I have changed the form controlbox from true to false, it is same for maximizembox and minimizebox. When I move the form titlebar, the form are still moving. How do I avoid the form from being moving on the titlebar
View 5 RepliesSo you know how when you call "Form.ShowDialog" from where ever you call it, it blocks until the form being displayed closes. And then the function returns whatever result it was.I want to know how to block like, but without a form, yet still have the "main ui thread".Basically I have this long process that needs to thread out and do several things... and it's heavily event based. It jumps between two threads, the main ui thread, and it's own background thread. The main ui thread needs to have access so that I can randomly open different dialog boxes for things... sometimes they're just windows asking to hit OK or Cancel to continue, others it's to perform some action, etc etc.
But there is NO central form related to it. It's a complete background thread running that randomly hops over to the main ui thread for things.Right now I have this class I designed called lets say "DoJobProcessor". On it is a function called "BeginDoJob" that threads off from the thread pool... when ever I need to jump back I use a ManualResetEvent to block on the background thread, jump over to to the main thread with "invoke" and passing a reference to the MRE, then release the block when done there and continue on on this background thread.
All while this is going on I just set the form I'm trying to block the main ui thread from managing by just setting its Enabled property false.It all feels just messy and annoying... and I was just writing something using ShowDialog and I was like... HEY, what if I could block this BeginDoJob method, hi-jack the main ui thread, then let that function return the result when done instead of having this "Complete" event with the return value in it. It's obviously possible because ShowDialog does it, but I don't know how.
This way the job I'm performing isn't always waiting for the main ui thread, instead its the other way around... the ui thread waiting for it, the way it aught to be. Show something, branch off do some stuff and just idle the display while it does it, come back show something else, branch off and just idle while it does that.
i have been working on an app, that remains just my preset sizes. recently, i have discovered that by double clicking the form title bar, even w/the formborderstyle being set to fixedtoolwindow, the form still maximizes and all of my controls remain in the top/left corner.. not a good view.. so, i set the maximum size of the form, and now when double clicking it, moves it to the top/left of my desktop.. not a good result. here is a quick sample to start w/.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

how do i permanently block the double click on the title bar, to have no effect on the form? i do not want to end up w/having to create a borderless form just to avoid this..

I have already done the creation of button and the dragging of button at runtime already.But now i need to know how do i save the last dragged button on the form and also detect the name of the last clicked button.so lets say i now drag a button to coordinates 25,254. so when i exit the form and the next time i launch it, the button will still be at 25,254. and this one will go on for the number of button i created like 100. so when i launch the form the 100 button will be at the exact position where i last saved them.the second part is lets say i created button1 and button2 on the form in runtime. so when i clicked the first button, it should display button1. and if i clicked on button 2, it should say button2. same goes for like 100buttons.

I have created a button in a UserControl. I have added that button to a WindowsForm in another app and added a buttonclick event to the code. When running (debugging) the app and clicking on the button; nothing happens. It doesn't act like a button at all.
The code for the button click event in my test app is as follows:
Private Sub Element1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Element1.Click
MsgBox("The button has been clicked")
End Sub

1. Something similarly I want with another button - when I click button2, I want to remove specific object - let say panel2, not hide it.
2. The second thing is that I want to put text from my textbox into excel, but in specific row. I would like to do that with word file as well. I would like to put text form my textbox in specific table, or row, or line. I only know to put text into a file.

On each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip
I am busy with a Windows Forms application.The purpose of the application is to convert Excel documents to HTML format so that they can be published to a website.I have most of the code finished and the application is looking really good.I have although encountered a problem. On the Form I have created an Export, File and Edit button.With the edit button I would like the user to be able to select whether they would like to save the 1st,2nd,3rd sheet and so forth.
I would like to create a window/Form within the edit button that would say something like "select excel sheet" along with a save button where the required sheet number could be saved or selected as a standard save procedure everytime.I know that I need to do this with the settings.settings control. I have tried numerous ideas up until now but it continues to baffle me.
Here is my goal.
1. Put a button on a form
2. User clicks the button and Monthcalendar pops up, then user choose a date.
3. The date that user choose becomes a value of a text box.
I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?

View 1 RepliesI need to make a save button. The user will work in main form. User also has Settings in the MenuStrip, when the user clicks Settings a new form will open. There user has ability to make changes that will affect the Main form. This is the code:

bib.Panel2.Hide()
End If
This is the change that the user will be able to do that will affect the Main form, but I'm not really sure how to make that the CheckBox1 will be saved when the user clicks it and the clicks OK button. I also want to know how to make a cancel button.
