Lets say that I have a form called "frmMain". There is a button on there that will launch a Modal pop up form. Any idea on how I can make the frmMain go to a grayscale or disabled look when the modal form is shown? I'm trying to make it so the modal form "pops" a bit from the main form interface.

View 3 RepliesI have a windows form that contains a panel (Hosting panel for X number of panels). The hosting panel AutoScroll property is set to true.I need to create X number of a panels each will have (Lable and three Radio buttons) at run time. The panel controls must be aligned.So I created a loop in my form load event to add the X number of the panels on the form. I used the location X and Y to position the controls on the form. The loop work fine until it reach the point where the controls host panel needs to enable Auto Scrolling which cause the added panels to be shifted to right. The shifting happened once the host panel auto scroll becomes enabled.

View 1 RepliesHow can i best make a movable widget within a windows form application? I wanted a area inside the form where the widgets can be placed / moved, i was thinking something like Windows desktop gadgets, where you can move them around and add/remove them. i was thinking of using a group box to contain each individual widget (notepad, time, calc ect) and a flow layout panel to contain and move all of the widgets.
Also i was hoping there would be a way to actually have icons to press which place the widgets into the flow layout panel.
The problem has been simplified for the purpose of clarity. I want to make a windows form application that uses an access database. The application will store the list of person's basic details such as name, age and country. The database contains two related tables ie person(id, name, age, country_id) and country(id, country_name) My windows form contains TextBox, DateTimePicker, ComboBox for Name, Age and Country respectively. Now I want to make CRUD operation Programmatically (Not using Visual tools) in the same form with some navigation buttons.

In my program, I created a list of a class that contains 5 picture boxes, a button, a label, an identifier, and some other stuff. I've got roughly 65 of these in this list. I'd be stupid to hard code all that in. The identifier is a 2nd way of identifying which specific location I'm working on.
Anways, all this is created at compile time. Works perfectly fine.
I then manually start a background worker that pings a collection of components. Based off the success of those pings, the picture boxes are enabled or disabled. Basically a proactive way to see if a collection of devices over multiple locations are actually working.
It's the background worker that fails because of thread-safe calls.

View 4 RepliesI need to extract 8 bit grayscale image.
My plan is this:
1. input the picture to a picture box no 1
2. load into memory
3. extract all value to a 2D array matriks
4. process the picture
5. Show the result in picture box no 2
6. End
I met a serious problem when i want to load it to memory. For a faster process i use Graphics class (i've got this trick from my friend). but later I found out that graphics wont work for PixelFormat.Format8bppIndexed.
Here's the code:
Imports System.Drawing.Imaging
Imports System.Runtime.InteropServices.Marshal
Public Class LockImage

Any code for creating the pallet for a Gray scale image, to display it on a picture box? I have written the code for creating for palette for a RGB image which is as follows:
Marshal.Copy(Image_bufffer, 0, _pImg, 1024 * 1024)
myBMP = New Bitmap(1024, 1024, 1024, System.Drawing.Imaging.PixelFormat.Format8bppIndexed, _pImg)
pal = myBMP.Palette
For i As Integer = 0 To pal.Entries.Length - 1
pal.Entries(i) = Color.FromArgb(255, i, i, i)
Next
myBMP.Palette = pal
Picturebox1.Image = myBMP 'Show the image
But the image displayed looks dull(less brightness) than the same image viewed from ImageJ. So instead of creating pallet from color.Argb, is there any way to create palette for a gray scale image?
I am trying to develop a image processsing application that will analyse some grayscale images, the images in question are basically biological photographs(PCR GEL Photographs) that have some bands which are lighter in shades, and these bands are arranged in some pattern( Mostly linear), Till now, i had suceeded to programatically identify those bands which are distinct and clearly seperated from other band, but the band, which are close, could not be identified as seperate band.more over my algorithms fails miserably in case case of color photographs,and i am clueless for a better approach.
