Forms :: Restore Default Color To A Control?
Jan 5, 2011
I am building a data entry form. I have code that runs when the 'submit' button is clicked to check that all required fields are populated; if not, the missing fields are hilighted in red:
Sub validatefields()
saveOK = True
If Trim(Me.cmbBillCat.Text) = "" Then
saveOK = False
Me.cmbBillCat.Appearance.BackColor = Color.Tomato
End If
My problem arises when I want to reset the color back to normal. In my form when you click Cancel or move to a new record, all fields are disabled (set to read only) until the 'Edit' button is clicked. Visually this is represented by the field backgrounds being gray. VB.Net automatically changes the text box/combo boxes backcolor to gray when I disable them. However, once I have explicitly changed a control's backcolor, thereafter disabling it does not change its color to gray.
[Code]...
I have tried changing the backcolor to System.Drawing.SystemColors.Window, but the problem is the same. The control whose color has been changed is disabled (won't accept entry) but the backcolor remains white, no matter how many times DisableFields() is issued.

I have a TextBox that displays a color as its background color and the background color code in its text. I have set the text color as Black.The problem is that if the user sets the color as Black then the color code will be unreadable. How do I set the text color programmatically so that it becomes readable when the user selects any color?

i'm making a vb aplication (only my second one so dont be to cruel) and i'm just wondering how to make it so that when somebody closes my aplication down and open it back up it restores it to the same state, i've had a look on google and the only thing i can find are how to remember the size and position of the form using the registry and also using flat file databases to hold the values of all the text box's but is there an easier and more elegant way

I have created an app which has a timer control which, when activated and meets a certain criteria, launches a second form with an alert for the user to review and action. this works just fine. Except.... when the main app is minimised and has lost focus, instead of launching the second form to a normal windows state it opens and sits in a minimized state itself and just flashes. How can I get the the second form to restore to a normal windows state?I have tried form2.focus and tried the windowsstate=normal etc but I'm still barking up the wrong tree.

Essentially what I want to do is copy a WebBrowser object such that I can do the equivalent of "Open In New Tab" or "Open In New Window" actions, maintaining any posted data. I don't just want to navigate to the same URL as in the original WebBrowser object, rather I want to repeat the HttpWebRequest.

In design mode - how do I change the default back color of buttons? I am using a white font and can not see the writing with the back color. The backcolor is transparent so in runtime it is fine (back color goes to blue and white shows).

I can change the backcolour on a form but I want to be able to change the colour making the change the new default color. The book I am using shows this as an example so far:
'show the color dialog and if the user clicks the ok button,
'update the background color of the form
if colordialog1.showdialog = windows.forms.dialogresult.ok then
me.backcolor = colordialog1.color
end if
end sub

In my program I have a picturebox. using the .onEnter and .onLeave events for the mouse I have the cursor change to a cross (one of the default cursors) and it does like a transparent grayscale thing and changes color a bit depending on what is behind it. The issue with that is that all the images I look at are grayscale images so it gets a bit lost. I am wondering if there is a way to use this default cursor and apply a different color to it?

I have a form with buttons, and the user can change the colors of the buttons with the color dialog box for fun:
Button_Play.BackColor = ColorDialog.Color
There is a reset button to put the colors to how they were without any special coloring, but I can't get them to go back to how they originally looked.They go to gray in the middle, instead of the nice shaded blue/gray style. I have tried a few different things:
Button_Play.BackColor = Button.DefaultBackColor
Button_Play.BackColor = SystemColors.Control
Button_Play.BackColor = Color.Empty
I am using VB '08 Express on Win XP with the Desktop, Display Properties, Appearance, Windows and Buttons: set to Media Center Style and Color Scheme: set to Energy Blue. how to (with this theme) get the button to look like default after changing the color?

I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.

I have a form that runs a report to pull info. (Not sure if this is even the correct subforum to put this on)And what this query is supposed to do pull info from combo box based on the start and ending numbers of orders for customers, but what I want to do is default the ending number to be what the starting number was as soon as the starting number is entered, but allow the user to change that if they want. I just want to make sure that it has a value. I tried to set the field to required, but that doesn't seem to be doing the trick.

I believe one or more versions of VB.Net did away with "default instances" for Forms.
1) Was it in the 2003 or 2005 version(s)?
2) With the more recent 2008 and 2010 verions, is it possible to use a template or
change one of the files in the project so that default Form instances are not created?
I was recently looking at some of the other .Vb files in VB.Net 2008 Express Edition.
By the way, just so you know I could install a full version of Visual Studio if need be from;
2203, 2005, 2008 or 2010

I'm using Visual Studio 2008 writing a Windows Forms project and I'd like to know a way to step around 'default instances' of forms. I don't like default instances, they constantly get in my way, and working in a team it's causing some really annoying confusion about the object identity of which form is actual in focus at this moment. This means I need to go threw the entire project (big) and remove ALL references to any 'default instance' of a form. But this is difficult to do as there's no errors or anything, it basically requires me to search for every text of "MyFormType." and then checking if it's accessing a default instance and fix it like that.
It'd be nice if I could just turn it off or something so I could
1) easily find all erroneous lines of code
2) avoid the accidental use of it in the future by anyone on the team

When I set a control to "enabled = false", I want the textbox backcolor and forecolor to remain clear and distinct (white and back - respectively). Is there a place in VS 08 where I can define default appearnce for disabled controls? Or is there a beter way to lock control values other than using "enabled", that woulddn't affect apperance?

While modifying my form, I was suddenly unable to place any of the controls onto the page - i kept getting an error:
"Components cannot be added in localization mode. Select Default in the Language property."
So I set my language to Default...thinking that perhaps it had somehow gotten set to another setting. That seemed to fix it...I could now add controls to the form. Suddenly however, when I run the form, I notice that my new changes aren't there. If I re-set the language property to what it was before setting it to default, I see the form I see when i run it...it's like there's 2 forms.
