View 8 RepliesEnabling And Disabling A Control?
Apr 12, 2011I am enrolled in a class in Visual Basic 2008. I wanted to drop the class, but it is too late. Now, I am stuck with this project that the professor assigned and it's due this Thursday. Anyway, how do I do this: The credit card number TextBox control is dynamically enabled/disabled depending on the choice of payment type? And did I do the newOrderButton correctly (see code below)? This is also the clear button. And is there a way to do a reset Form? Sorry for that many questions. I am really lost right now because there is a lot to do in this project and I don't even have a clue of how I am going to finish this project.

More Window Enabling / Disabling Troubles
Oct 31, 2010when I got home to try out the method in the above post in my real application things did not work out.The big difference is that my main form is a MDI. When I open my edit form, it's mdiparent is set to the main form. When I click 'edit' and then disable "me" the entire application goes modal.I was expecting only the MDI child to go disabled, not the whole application..Basically, I want only the MDI child window that opens it's "edit" dialog to go disabled..

Containers - Why All Contained Controls Within A Groupbox Do NOT Respond To Enabling / Disabling
Feb 10, 2011I'm working on a winform which contains several controls like textboxes, radio buttons, datagridviews... All of these controls have been added to a main group box called gbDataEntry. My problem is when the user is seeing the form, I set gbDataEntry.Enabled = False but I want to enable some controls like DataGridviews so the user can scroll them. After disabling gbDataGridview I set DataGridView1.Enabled = True but it seems that the datagridview does not respond to this line. Why?
View 1 RepliesEnabling/Disabling A ToolStripMenuItem Programmatically Does Not Enable/Disable The Object
Jul 15, 2009I am developing an application with a DataGridView (dgvData) that requires a ToolStipMenuItem (tsmiSelectNetwork) of a ContextMenuStrip (cmsNetwork) to be enabled and disabled programmatically based on if the column is sorted or not.
I have set:
'tsmiSelectNetwork.Enabled = False' at runtime
'tsmiSelectNetwork.Text = Select All' at runtime
'dgvData.Columns(5).ContextMenuStrip = cmsNetwork' programmatically
When dgvData is sorted by column 5, tsmiSelectNetwork.Enabled should be set to True; when it is sorted by any other column, it should be set to False (see code below)

Hscrollbar Freezes And Control Jumps To Front After Clic And Enabling/disabling?
Jan 14, 2010I have successfully ported a VB6 application to VB.NET (VS2008, .NET 2.0). Much optimization and rewriting has been done, but there is one possible BUG i cannot overcome. I have a standard HSCROLLBAR control used for accepting a numeric input. The control needs to be disabled during complex computational routines to prevent additional user input. I am setting the enabled property to false and reenabling the control at the end of the calculation cycle. The control is enabled and disabled a few times, because some code has been placed in the onpaint event of a drawing area, and separating the calculation part from the drawing part will be a huge task.
Large changes are handled correctly. Small changes aren't. The problem is that the control freezes in a unknown state after clicking on the arrows. A second click makes the control (and its parent control box) jump up and over everything else in their container.The scrollbar remains functional only via the contextual menu. This happens both in debug and release builds. There are no overrides. Coding/Test platform XP SP3 (more than 1 machine).
There is no code whatsoever that handles neither the parent control nor the scrollbar repositioning and resizing. The only code takes the value of the scrollbar and passes to the calculation section. If I omit disabling and reenabling the control, everything works fine.i tried rebuilding the control from scratch. forcing enabling the control after it has gone haywire does not make changes, disabling the groupbox instead of the single control doesn't make any difference, debugging step by step confirms that things go wrong when drawing the controls within the private system form classes.
Enabling Buttons After They Are Disabled?
May 13, 2012I attached a picture of how my project should look and what the labels are. There are a total of 12 books and 4 different age groups. In each age group there are 3 books. There is also a previous and next books button which will show the next book in that age group. I want to make it so that previous button is disabled when it is on the first book of each age group and so that the next book button is disabled when it is at the last book. The only issue that I am having is that after the button is disabled it is not enabled again after. Here is my full code for this part as of now. As you can see I made it so that everytime I click on a new age group the previous button is disabled initially.
I took some unnecessary code out of here because I don't want anyone from my class finding this and coping all of my work.
Public Class BookInfoForm
' use this array to display information in this form
Private books(,) As BookInfo = getBooks()

.net - Can Disabling A Control Cause A Radio Buttons Value To Change
Sep 22, 2010I have a For Each loop going through the controls in a panel disabling them. When the loop reaches one certain grid control and disables it the CheckedChanged event fires for the next control in the loop which is a radio button.
The call stack is as follows:
System.Windows.Forms.dll!System.Windows.Forms.RadioButton.OnCheckedChanged(System.EventArgs e = {System.EventArgs}) + 0x15 bytes
System.Windows.Forms.dll!System.Windows.Forms.RadioButton.WnProc(Microsoft.AGL.Forms.WM wm = WM_RADIOBUTTON_NOTIFYVALUECHANGED, int wParam = 0, int lParam = 0) + 0x17 bytes
[Code]....
I don't understand how control.Enabled = False can cause the OnCheckedChanged event.

View 2 RepliesVS 2008 - Activating / Disabling Controls Based On Date
Mar 19, 2009I have this form with a bunch of input controls. I have code working that will disable them all like I want, but need to work with the if/then statement portion. Basically, it's a "History" form for patients. There's a date field for each entry, and if that date doesn't match the date you're accessing the form I want it to disable all controls so you can't edit the form. So it would have to check the current date with the date that is on the form. Then I also want to have an override button that will ask you if you want to enable all controls anyway, which I can probably figure out. There is some older VB6 code (I think) but I know nothing about VB6 or how it translates.
I think this is the portion that does what I want in VB6:
Private Sub DATE_DblClick(Cancel As Integer)
Call Setdate
Exit Sub
Dim sysDate As Date, Response
sysDate = VBA.Date
[Code] .....
How to have the program check the current date with the date in this form. From there it's probably just a simple if/then statement to fire off either sub. This date control on the form is a DateTimePicker. Maybe I just have to compare that to the system date but I still don't know what to call for that.

Resolution And Buttons - Tabs, Inside Each Tab There Are Buttons (the User Can Add The Buttons When They Want)
Mar 3, 2012I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?
