Is there an "easy" way to change a control's ForeColor when it is diabled? Yes, I know that this goes against the Windows standard.
On our forms, we have buttons with a dark blue background and a white foreground (the design is dictated by marketing). When the buttons become disabled, the ForeColor goes to a dark color making the button unreadable.
I need to allow labels in disabled panels to retain a their prominent forecolor. So, I am considering replacing all labels in panels that become disabled with LinkLabels. By disabling the control and setting its disabled color to black it holds the color. However, I have always been of the opinion that one should use the lightest control possible.

Is there a way to change the forecolor and backcolour of a piece of text inside a textbox or a rich textbox?
I have an ap that requires the user to fill in information in certain areas in a richtext box. The areas that the user needs to complete is colored blue. To give the user some cue that input is required, I would like to change the mouse pointer when the pointer moves over blue text in the rtb.

View 2 RepliesIn runtime I'm programmatically changing the forecolor to all label and radiobutton controls placed in the groupbox.
The only thing missing is to set the groupbox text/caption forecolor, but as soon as I do so programatically all controls in the groupbox inherits the font type and color making the text hard to read on the Button controls placed within the groupbox.

View 2 RepliesWhen 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?
View 4 RepliesI am making a configuration screen so that an administrator can easily determine what controls on a form are enabled according to a combo selection.
I have created a table (SQL2008 DB) to store the settings and need ideas how I can best implement.
The session form will start up normal with only a few controls enabled to start, but then when the user selects a "session type" from a drop down combo then the form will be configured for that type. Because there may be several different combinations, and I do want to offer the user the ability to add and configure more types as needed I feel like this may be the best method instead of hard coding.
Table Structure
SessionType varchar(25) not null PK
ControlSwitch varchar(50) Not Null
(Edit: I may add an additional DB field so that I can specify the default value of a control also)
Now what I thought I would do on the config form is have a series of combo boxes and the label represent each control with a value of True or False, then when saved it builds a string like example 1,1,0,1,0,1,1,1 or True, True, False etc.
The string would represent
ctrl1=on, ctrl2=on,ctrl3=off,ctrl4=on,ctrl5=off,ctrl6=on,ctrl7=on,ctrl8=on and so on.
Let's say I've got a TableLayoutPanel with 50 cells in it. Inside each cell is a separate text label. If I want to change the color of each of those 50 labels at run-time to the same color, is there an efficient way to do it? (so that I don't have to write 50 lines of LabelX.ForeColor = X, etc).
Not that I would mind writing 50 lines of code for this, but I would like to figure out the most efficient way to do this sort of thing, for future reference.

I dynamically add picture boxes to a vb.net form. However, when I add the new picture box, it is always under/below/behind the picture boxes that I previously created. Is it possible to change it so that the newly created picture box would always be in front of the others?
View 2 RepliesI'm trying to change the look of some controls in VB.An example would be a button, I now have a stack of 4 images on top of eachother. By using the mouseover events and such, I get the same result as a normal button. However, I'd like to be able to insert those images into a normal button like thing.
I know it's possible to do this by creating a custom control, but that'd end up with the exact same code, just in a different file.
However, the real issue would be a dropdown box and slidebar. I'd like to get them to look nice with my theme. (Background, buttons, borders. Things like that..). I got absolutely no clue on how I should do that.
I know that there's a tool to create controls, but that's from scratch and I can't get a grip on it, at all.
What I am trying to do is have a Form which can dynamically change the controls which are on it and their properties; this allows my main GUI to be more fluid and not have tons of groups and controls on it which I must hide and show when needed. To make this as extensible and reusable as possible, however, I want all the control additions/subtractions/edits to occur through a separate DLL which I write. The problem is, I can't seem to instantiate any controls in the Class Library because I cannot import 'System.Windows' or any of its children ('Forms').
View 9 RepliesMy program has two lists, one a listbox and the other a listview viewed in details mode.
Both of them change heights (get taller) for no obvious reason. I am having to add a call to a method that resizes them to the end of every method, which is kind of absurd, I think. Also, when the window size is changed, these components change size, which means I have to keep track of that.
Edit: I had also thought of adding a timer to handle this.
I m implementing control based security in my application. where i m saving controlname (per form) in database, which are to be restricted. So far I have implemented the security and restricted control get disabled.
Now what i want to do is that i have to prevent that for those controls the "control.Enable" property should not change. how can i restrict that.
I have achieved the functionality by canceling enable=true property in "Invalidated" event of the control. but this is not some generic way. I have to map this event for all controls in all forms :(.
What i really want is that as all my froms are derived from same parent which implements the security. so the parent should some how restrict enable property from changing.
So,HOW CAN I PREVENT CONTROL enable property from changing in their parent class?
I have come across a problem with visual studio 2010 & vb.net. i have a few custom controls on the form and few standard controls. When i build the application, the custom controls automatically change size and location. Anchoring and Dock properties are fine. Anchored to Top Left without dockstyle. Even if i fix the location and size in design mode, after i run the application the controls again change back to weird position.

View 6 RepliesAll my forms inherits from one base form where we handle background paint and set standard properties. Recently, I think of cheching if the app is running on Vista or Later to use Segoe UI font, and I added this. The problem is than inherited forms changed sizes and their inner controls changed also... even PictureBoxes! The controls and forms seems to be thinner (in width), so square picturebox became vertical rectangules!

View 10 Repliesfirst post here at the forums. I am a complete noob when it comes to VB .Net, but I have done a lot of VBA programming and some VB6 back in the day. I have posted this question on two other forums (including the MSDN forums) and no one has responded so please let me know if I need to clarify the question.
I am (trying) to write my first .net app which reads/writes data to a device connected over the serial port. I have manged to get it to work to send commands to the device and receive the reply back, mainly using the info from this article: Beth Massi - Sharing the goodness that is VB : Reading from a Serial Port and Saving to a Database
However, I am having problems with updating the controls on the main form based on the received data from the serial port. Basically I want the user to click a button (one of six on the form) which will send data to the device, then based on the response from the device, the BackColor of that particular button, will be changed accordingly. I just am missing something b/c the button click is a different sub than the sub that handles the form controls update and I can't get the two to talk
