VS 2005 : Pick Specific Parent Control?

Dec 11, 2011

I have a form with a tabcontrol(6 tabs) with a groupbbox on each tab page containing numerous NUDs. The NUDs need to be checked for either 0 (double) or 0.0 (decimal). I don't want to have to do this over and over:

vb.net
If Me.nudLinealFeet.Value = 0 Then
MessageBox.Show("Lineal Feet cannot equal 0.", "No Value Given")
End If

[code]....

but I can't figure out what to do since there are more than 1 "parent controls".

VS 2005 Linking Up All Parent Events To Child Control

Mar 10, 2010

I have a user control and a panel on it in Dock fill format. Now this is exposed for the user to add on the form. Till this point fine. Now the user sees lot of events for the user control, which I want to actually link up with the panel on the usercontrol, because that is where I want things to happen . Is there any solution to link up the events in few lines of code than calling each event separately? I am also looking to expose only few events than all the base control events.

Pick A Word In Combo Box A That Has Specific Words/phrases In Combo Box B Show?

Feb 24, 2009

i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.

Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' fills the combo boxes with values
Me.xGeneralComboBox.Items.Add("Soda")
Me.xGeneralComboBox.Items.Add("Juice")

Order Of Creation Or Adding To The Parent Control Determines Whether Or Not A Control's Dock Property Supersedes Another's

Jun 17, 2010

i frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?

Bind Property Of User Control To One Of The Parent Control's Fields?

Dec 30, 2011

If I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.

Dispose Of Each Child Control Before Disposing Of Parent Control?

May 22, 2010

I am using Visual Basic .Net 2005 professional.From what I understand, I should be disposing of any object that is an unmanaged resource. I understand the best way to tell if a resource is unmanaged is if it has a Dispose method. ie: If I type a dot after my object, intellisense shows .Dispose() as one of the options. If it does, it's an unmanaged resource. Is that correct? In that case, pretty much every control is an unmanaged resource: buttons, forms, panels, etc.In the application I am working on I use an MDIparent container form, which contains MDI children forms, which themselves contain Panels, Menus, Groupboxes, etc, which in turn contain Buttons, Textboxes, Labels, Dropdowns, etc.Do I have to dispose of each button, textbox, label and dropdown within a panel before disposing of the panel?

Do I have to dispose of each panel, menu, and groupbox before disposing of the MDI child form?.Or can I just call the Dispose() method of the MDIchild form and the GarbageCollector will take care of all the controls and resources within the form?Watching the "mem usage" in Windows Task Manager seems to be an unreliable way to detect if I have a memory leak. The numbers just keep climbing and falling (mostly climbing) erratically and without any activity performed on the application. Is there some (relatively) easy way to detect leaks?

[2005] Custom Scroll Bar For MDI Parent?

Oct 15, 2008

i have a MDI Parent. As you know a MDI parent can have scroll bars. I want to make customized scroll bars. Meaning instead of windows default scroll bars i want just to images / buttons (arrows (up/down)) that when clicked will scroll up and down, and then others for left and right...

How do i do this? I dont want windows default scroll bars to appear.. i know can disable them but then is there a property / method to scroll in a direction, let my code do the work.... i would also then want it so as you scroll my custom scroll buttons wont go away, as you scroll they should stay in the same spot.. i think i can do that by a panel and docking, so that isnt important.

Create A Control And Set It's Parent To The Picturebox?

Mar 28, 2011

I'm creating an app for school to mark targets that we shoot in shooting competitions. Now I have created a dll in C# to do the marking bit and it works.Now the problem I am facing is that my app gets a image from the scanner (A4 size @ 600 dpi) and putting it in a picture box.There will always be 20 targets to be marked per image( However I want this to be able to vary to provide flexibility) My dll accepts a image that contains a single target so I need 20 individual images of targets.Create Drag able Rectangles in the picture box and crop the images from there . There are 2 ways of accomplishing this.

#1 Create a Control and set it's parent to the picturebox. (This should provide a location relative to the picturebox Right ?)

#2 Use only GDI (eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeew)

so my choice would be to create a control except I have never created any control from scratch and I have no idea how to do the visual drawing part of a control.

Set Parent Control In Design Time?

Jun 11, 2012

I created a custom control (inherited from a panel). Then I created some other custom control (textboxes)

I add the panel control to the form, then I add some custom textboxes inside the panel.

Now, if I remove the panel, the custom textboxes don't move. I think, because the custom panel control isn't the parent control of the custom textboxes.

How can I modify my custom textbox class, if I add the textbox to a form, to a panel, to a container, it should have that container as parent.

Parent-child Relationships Of Controls In 2005 Express

Jan 10, 2009

In VB6, if you put a picturebox on a form and then put a control inside the picturebox, then the control would be a child of the picturebox. Its location would be relative to the picturebox and not the form.If you do the same thing in VB 2005 Express , the control seems to still be a child of the form and not the picturebox (i.e. its location property is relative to the form).Is there any way to make a control or graphic inside a picturebox a child of the picturebox and not the form?

Asp.net - Can A Web Control Edit Properties Belonging To Its Parent

Jul 14, 2009

I have a .aspx page that loads three separate .ascx controls to represent adding, editing and listing objects. It currently simply swaps out visibility and enables/disables the controls to switch between pages.However, when listing objects (in a gridview), we offer the basic "Edit" button beside each one. Clicking on this will, obviously, load up the edit control for that user. This functionality exists inside of the control, rather than the parent page. Is it possible to modify attributes for the parent based on events occurring in a child control? (For example, change the visibility and enable/disable the other children controls)
