VS 2008 Remember Textbox Text when Form reopens
View 2 RepliesI'm writing an application in which a user can add, change and delete members from a list of members, and the adding and changing is done in a dialog box with some input fields.The problem is that when the user presses the OK button it should test whether some combobox is still empty, since this will otherwise return nothing and that will create an error somewhere else in the program. I do this within the OK_Button_Click event of the dialog box by testing whether the selectedItem is equal to nothing, if not it calls me.close, but if it is equal to nothing it displays a messagebox indicating that the user should still pick something from that combobox.Now the problem: when the OK button is clicked in the messagebox the dialog box also closes, even though the me.close isn't executed.

View 2 RepliesI'm making a program when the user clicks the button it displays the number of rolls it took to get snake eyes ( 1 on each dice) I have randomized it and in the Do loop it calculates until it gets the right code. I just need some help with the code that will display in a listbox the results that didn't get picked for snake eyes.

I know that with some of the programs I use, when you click on an item to change it's color, the color dialog will actually show the current color and it's rgb value.
I'd like to do that in my application but can't find the answer on how you do it.
To change the backcolor on a textbox, the user double clicks the box and it shows the color dialog.
I think I have all the properties set right -- fully open to show custom colors etc.
BUT, it doesn't show the current color.
They all have 0 0 0 rgb.
Why isn't this working? The color dialog comes up, but when you choose a color and click 'OK', nothing changes.
Code:
Private Sub ColorBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ColorBtn.Click
Dim NewColor As New Color
[CODE]...
How can i use the color dialogue to return the color selected as a string? So if i was to select red i would like the return to be "Red" and so on so fourth.Another thing i would like to ask is if it is possible to return the color selected as a string in hex color code form (like what is used in HTML for example #FFFFFF, #000000 and so on so fourth).I have a feeling though that it can only be returned as R G B integers but maybe there is a way of converting these to hex color codes?

I often use the process of displaying a dialog from a form, with the dialog user input then used to update the main form without any problem. In a new scenerio I launch the main application screen, I then show a login dialog ontop of the main app screen and can launch another dialog from the login if a new user is required. The plan is to update the login dialog (updating a combobox to reflect the addition of a new user) from the new user dialog.
See code below :-
'Update login forms user list as new user added successfully
frmRoomBookingLogin.cboLogin.DataSource = Nothing
frmRoomBookingLogin.txtPassword.Text = "Updating password from dialog"
MessageBox.Show("The password text is " & frmRoomBookingLogin.txtPassword.Text)
[code]....
The messagebox implies the dialog has been updated yet the text does not change. Is it possible to update the dialog when using a setup such as Form -> dialog -> dialog? I'm intrigued as why the dialog does not reflect changes. I have never refreshed/repainted the dialog as never required to in my other examples when updating a form from a dialog and never encountered a problem when using a two tier form setup.

I have a small project that requires me to have a font dialog, a color dialog and a print dialog. It has four text boxes that are formatted based on the font from the dialog and the color from the other dialog. I am to print it all out with the same font and color. I have easily put the font in the right place and have the rest of the print set up, but the DrawString wants Brushes.<color> for it's color. How do I make it the same color as in the text boxes? I am not trying to get you to do my HW for me, but everything I see online is the brushes or shapes... if you could suggest something to look into that would be great, but I doubt my grade would be much affected by my printing everything with Brushes.Black like everyone else in the world seems to be doing...
