View 8 RepliesI been playing around with some code I found on internet and I am probably almost where I need to be. Using the printdocument I am able to get the active form in my project to print. That works fine. MY nextr issue was to get the form to print so that it is Black & white. No shading etc.. So I found a routine on internet that will take image and turn to B&W. Problem: IF a text box fields background color is too dark then the entire box shows up in black. If a text box field data is Selected it also is too dark and comes out white.her is code I found for turnign to B&W
Public Function PureBW(ByVal image As System.Drawing.Bitmap, Optional ByVal Mode As BWMode = BWMode.By_Lightness, Optional ByVal tolerance As Single = 0) As System.Drawing.Bitmap
Dim x As Integer

He wanted to know how they can do to convert a portion of the form that you see only blue or black and white. I mean, the user presses a button and all that is in the form sees only blue or black and white only.

I see that the Line method is replaced with DrawLine, however; it seems like DrawLine must treated as an object as follows:

I have a form with transparent background (using png file).All controls placed over it becomes black at start then they change there color and comes to there original state on MouseHover. Its not the transparency keys problems since the transparency key color is different that controls back color. What can be the problem?

I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?
Im trying to create a stopwatch in one form and another form show my progress bar using a combo box for mins and seconds to show the progress bar on form1 1
[Code]...
I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

Using the code below:

This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?
ETA: The problem does not occur if I open the form using a key.
This is a database app where I am trying to check for possible duplicates and give the user the option to keep the new record or assign to an existing record.In form1 the user will enter data into a textbox. I use this information to build a bindingsource.filter. Then I call another form (form2.show()) to display results to user and get user response. This part all works correctly.
The problem is that as soon as form2.show() executes, I loose the contents of the textbox - and it appears that I am no longer in the bindingsource.addnew() method.

or is there another suggestions

View 2 RepliesI have a series of methods being called for my networking code. An event gets fired from the networking thread. Inside this event, which I've hooked into from a singleton class, I route messages to form level methods which they register on form load to handle certain messages they care about. Inside of these form message hooks I need to close the current form (which I was able to do) but also show a different one (which is giving me the trouble).

I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
I've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog()but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong.
When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it what may cause this to happen, or what I should be looking for that might be causing the problem??

View 1 RepliesI'm currently making a huge project. So huge it is split into four separate applications. I want the form to fade to black once the user logs on and only fade up when the new program has fully loaded. I've tried various methods, such as having the second program write to a file on the C: drive, then have the first program wait until that file exists to fade out.Is there a more efficient way? My method isn't working... the form will fade to black, but you get a glimpse of the desktop just before the new program launches (both are full screen apps btw)
