I added an image as the background image for a form in VB.net. When I run the program, after approx. 5-6 seconds, the image partially overlays itself, as in an offset overlay of the underlying image. I never had this problem in VB6, but I did have it the other time I used a background image on a form in VB.Net.
View 1 RepliesI found that the overlay function was working fine. However, it seems that if I use the overlay function while reading an image from a stream, that it would enlarge the picture before overlaying it.
ie:
overlay = New Bitmap(stream)
g.DrawImage(overlay, 0, 0)
Seems to enlarge the image before overlaying it, whereas this:
overlay = New Bitmap(My.Resources.Pic)
g.DrawImage(overlay, 0, 0)
Seems to overlay the image fine.
What could be the reason for this?
Background of form: black
background of char, bombs and shrooms: transparent
picbox behind char, bombs and shrooms is regular (marioland)
How can i fix it so the transparent parts dont see form as background but marioland as background?
I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?

View 1 Replieshow i can refresh my main form background image once a user picks a different image as the background.I have 2 forms namely Form1 (main form) and form2 from where the user can select the image he or she would like to set as the background image of form1.But the problem is that after selecting the image file from form2,when form1 is opened the background image doesnt change and remains the same as before.Only when the user ends the program and re-runs it again the image changes.
I tried
Form1.reload()
Basically I'm trying to make a layout change on a form if a link label is pressed. My main form I want this on has a "default" layout with a background image in place. What I want to do is, name the link label "Plain Layout". When the link label is clicked, remove or "hide" the background image and replace it with the background color of "control". After this action is performed, I need the text to change back to "Default Layout" and "show" the image.

Just the option to browse and apply to a form.

View 1 RepliesI've been trying to make an image viewer that keeps top most while I do other things (like typing, etc), so I don't have to hop windows, or sacrifice screen real estate.I made a main form, and a configuration form (opened by pressing o), with options to set the main form's opacity (working), the picture displayed (as the form's backgound picture, not working), and if the main form stays top most or not (working).
Instead, the form just keeps displaying the image I set in the IDE.I first used a picture box to display the picture, which did not work, and decided I didnt need to have a picture box if I set the picture as the form's background picture.I tried looking at what could be going wrong, but couldnt find out much more than the path is being delivered to the main form.I'm working on Vista Home Premium 32bit SP2, VS2003, and here's the code.PS The code links to a D:ath-fin.jpg that I used as the default background picture, and the code is for 2 seperate forms.

Most likely it is the graphics class not measuring in pixels or something.

I have a transparent layer on the top of a form. I need to display only some part of that transparent form.
-edited- If you think of a map and traffic signal icons displaying on the map. There are a map image layer and a traffic signal icons layer, which is tranparent except icons. if you move the map location, the traffic signal icons should move along with. if the certain area of map does not appear on the screen by moving, corresponding traffic signal icnos should disappear as well. This is what I am trying to do here. Moving the trasparent form is straightforward, but I need to hide some portion of that transparent form.

[Traffic sig] here I need to show "fic s" part only.
This is for a very small image.
I have a problem concerning the Form_Loading event: When I want to load a new Form (ImageDisplay) the ImageDisplay_Load Event is not executed first.
Instead it runs through the global variables definitions and then executes a Private Sub called numericupdown1_changed.
The numericupdown1 field is part of the form I want to load and has not been touched.
That is my calling sequence:
Private Sub Dispalydata_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Dispalydata.Click
Dim myDisplay As New ImageDisplay

The strange thing is that for other forms in my code it works well and starts with the form_load function.
Is there a way to somehow "stabilize" the background image on a form, because the way it is now, makes it almost unbearable to use background images. I have a transparent panel that has a scroll bar, and when you use the scroll bar, the background image goes all "weird". It also starts flickering when you resize the form, and all in all, it's not that enjoyable to use.

How to remove or change the form back gorund image to "none" through runtime?
View 7 Replieswhat I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:

I am trying to create a VB.net form application to visually fill in a floor plan with different colours according to reservation status.The basic floor plan is white and the idea is to colour in the various apartments in different colours depending on some variables.I have tried overlaying .png pictures on top of each other but this doesn't work due to the non-true nature of transparency in visual studio as soon as you overlay more than 2 PNGs.Not much more success with drawing polygons either.
View 1 RepliesI have a mask bitmap (bmpMask) that I am drawing onto a destination bitmap (bmpDest). Both bitmaps have alpha channels but are already full of opaque content. What I want to do is produce transparent areas using GDI+ 'Draw...' methods on bmpMask so that bmpDest shows through when I draw bmpMask over it.Of course gMask.DrawLine(Pens.Transparent, 0, y, wMax, y) causes no change to bmpMask, because GDI+ works as designed and doesn't draw anything when transparent. Even with semitransparent colors, only the r,g,b values of bmpMask's pixels are updated.
