Form Opacity With Timer Control - Textbox Text Area Is Alway Clear?
May 21, 2009
I trying to fade-in the application startup form using the forms opacity and a timer control.I dont know if I am using the right approch to achieve this so suggestions for alternatativ approches are welcome.I have a form with a few randomly select controls on it, one of which is a textbox.When I run the code, the form and all its controls reflect the changes to the form opacity property set through the timer_tick event except the textbox.The textbox remains clear all the time and I would like to know: Why?[code].....

When I set the opacity of a form to 50%, the opacity of a label on that form is also set to 50%, but I do not want so, is there anyway to make a 100%-opacity-label with 50%-opacity-LabelBackground on a 50%-opacity-form?

From the visual code requests as you can guess i think a good GUI is very important in an App. What i want is to lower the opacity of my textbox so u can see the SWF in the background, is this possible?

I have a form with a PNG image as its background image. How can I make the form's opacity match the opacity at different parts of the image? (for example, I have a drop shadow that fades from black to transparent. How do I acheive this effect on a form?)

I need to be able to change my form's opacity without changing the opacity of the components.
I really only need to do this on one form in my entire app, so this is getting a little frustrating
I've been researching for about half an hour now, trying to figure out if it's possible, but I'm coming up short.
I've seen some WPF examples and if it really comes to that, I'm more than willing to change the app from a WinForms app to a WPF app. I've made a WPF app before, so I'm familiar with it. But, I don't want to have to remake my entire project for this one form.
On that note, does anyone know if I can make a WPF form how I need it and just import it into a WinForm app? It doesn't seem possible, but it's better to ask than not. I'll look into this more.

way to clear textboxes in VB.Net and what is the difference between the two methods? I have also seen people be critical of folk using clear objects on their forms and i can see why but in this case, i am only learning.
txtbox1.Clear()
or
txtbox1.Text = ""

I have a timer in vb.net and it's interval is 1000ms ,. i have placed in it's timer_tick event a code that will print screen the screen and save it to a database.The problem is when i click outside of the form, or loosing the focus of the mouse to the form containing that timer/printscreen, the timer stops. As a result the printscreen also stops.here are it's properties:
generate member = true
interval = 1000
modifiers = friend

if any one knows of a way to determine if a control is currently in the viewable area of the parent form. In example...if I have a form where all controls are visible when the form is maximized, how would I go about determining which controls are no longer visible to the user after they change the window state or form size. To be clear I am not talking about the visible property of a control but rather if the control is actually on screen for the user to see when they do something like resize the main form for instance.

I have a textbox with text (to tell the user what to put in the box) when they click inside the box, i need either all the text to disappear or it all to be selected so that it is easier for the user to enter the data but pref the first.
it is a textbox to collect the date (in relation to my other post) when the program runs, the DD will be displayed in a textbox, i need it to go when the user clicks to enter the day or to be highlighted/selected (NOT THE TEXTBOX, just the TEXT INSIDE)

I'm trying to write a Database manager in VB (2010) that updates a SQL database that compiles and summarizes my financial records. The code works, but I'm having issues with one exception that I think I understand, but can't circumvent. I've built an I/O form that enters a series of purchases and sales into a temporary datatable. After review of the list, the program connects to the database and executes the SQL. That all works and isn't a problem.

I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?

I don't know much about vb.net so I'm hoping this is something that can be done fairly easily. We currently have a system where valves are fired by checkboxes (representing each valve) being checked at certain intervals and when the last valve is switched the timer restarts in order for the sequence to repeat itself. We would like to be able to have a textbox in the form where we can just type in the interval at which the valves (checkboxes) switch without having to change the interval manually in the code each time we want to change it. Currently in our code we just have a set interval. Here's the code:

I have a reset button created in my VB form, but don't know how to code it so that it will accomplish what I want. I want it to clear the form's text boxes so that new input can be entered. I could just code an end statement but this closes the form, and I want to keep it open to continue working with it.
