Pixel Counter - Count The Black Pixels The Grey Pixels The More Grey Pixels
Jul 27, 2009I'm trying to make a -what i thought would be simple app.My intention was to build program that:1) i'd provide a grayscale image2) the program would count the black pixels the grey pixels the more grey pixels etc. (the hue) and the white3) would make the percentage sum of all pixels, that is: 300.000 black pixels (rgb 0 0 0) etc. given that 0 is the black, 100 the white. e.g a simple grayscale image is 55.2 white
This was my way and i don't think that is useful:
First of a button to convert the image to greyscale:
Dim bm as new Bitmap(source.Width,source.Height)
Dim x
Dim y
[CODE]...
Secondly, -and that's the stupid way- i did -or better i wanted to do- this: i put the code to dynamically create labels, each label having the colour of a pixel as background colour and as text the colour converted to rgb
The third step which i intended to do (i couldn't get pas two) was to sum up the labels etc.

VS 2008 Translucent Layer On Form?
May 12, 2010I am using normal windows form application. I wanted a way whereby I could create a layer over my form which would be semi transparent and nothing would be accessible until I click a button or do something like that. What I want is similar to a grey sheet that covers your screen in vista or 7 when user admin Yes/No box is displayed. Nothing is accessible behind. Or as you might see in some webpages where till we dont click a button or so the content behind is inaccessible.
Actually I want this to apply only on my mdi child form (a particular one) and it should enable me to see whats in the form but semi transparent and till i dont click a button on it, the content behind should'nt be accessible. Kinda like what you see in webpages whereby there is a button in the center and till you dont click it you can't select or click on content behind it.
Create A Form With Translucent ClientWindow - Looking For A Cleaner Method
Mar 5, 2011I wish to create a form with a translucent clientwindow but want to have all contained controls and the form border display as normal. Setting the form's Opacity level dims the entire form including its controls and this is not the effect I'm trying to achieve. I have achieved the desired effect by placing a second form behind the main form (with the main form's "TransparencyKey" property set) and adjust the background form's opacity level. This added a few issues to overcome in terms handling the z-order, handling click-through through the main form, and an additional form in the Alt-Tab sequence that I did not want.

VS 2010 Make Classes Import Into Main Form.vb
Mar 20, 2012I was just wondering how you can make classes import into your main Form.vb
Let's say I make a class with the following.

Public Sub HideMe()
Form1.Hide()
[Code]....
How could I make the Form1.vb include the things that are in OtherStuff.vb.
All of the solutions that I have tried come up with the same error. Reference to a non-shared member requires an object reference.

View 2 RepliesTopMost Form - Messages Form Would Be Hidden By The Main Form
Nov 20, 2009I have a tool window that I want to stay above the main application form, but not stay on top of all windows forms. Similar to the floating properties window for visual studio - it always stays on top of the main VS window, but if I select another program, like internet explorer, the floating properties window will be behind internet explorer.
What I have is an application that has several forms that may be displayed at the same time. I have a Messages form that displays messages generated by the code in the form, that gives the status of the application. Obviously, the user would not normally be working on this form, but they may want it to be visible to see the status messages from the program (File saved confirmations, etc). So, my two options right now are I can set the form to be on top of all other windows forms or, when the user clicks on the main application form, the messages form would be hidden by the main form.

Load The Main Form Of A WPF So That A Separate Thread Goes And Gets Data From The Database While The Form Is In An Apartmentstate?
May 15, 2012How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?

View 7 RepliesCalling Showdialog() On A Form - From The Main Form's OnLoad Event Makes The Modal Dialog Go Away After A Few Seconds?
Aug 7, 2009I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):

Accessing Datasets Loaded In Main Form From A Child Form?
Aug 11, 2009I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.
Create An IMAGELIST In A Main Form And Add To It Then Have It Accessible Within A Child Form?
Mar 22, 2011I want to create an IMAGELIST in a main form and add to it then have it accessible within a child form. I found several MS examples on database shared access but this is NOT the concept I am after. Straight forward:
Child_Form.<function_to_execute_in_child_form>(The_Passed_Imagelist)
So, within the child form it want to do whatever I like to the IMAGELIST! I have tried passing the object by reference and anything I could think of.
