Panel Based On Inches Not Pixels?
Mar 15, 2011
I have a Panel control where the dimensions of the panel are specified by the user in inches.How do I convert this to pixels so I can set the height and width properties of the control to accurately display on the monitor?From what I have found, there are 1440 twips per inch so I tried something like this:control.height = (userDefinedHeightInInches * 1440) / TwipsPerPixelYTwipsPerPixelY is 15 on my computer. The panel is not displaying at the correct size. It is too large.

I know that you can return the length of a string, which results in the number of characters and spaces. Is there a way to return a width of the string in say, pixels,inches or some unit of measurement.

I'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.

I've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!

I have a RTB. The entry is generally short, but the user can change the font, font size, bold, color, etc. When I print it, I want to make sure that it does not exceed a single line. In my case 5 inches. How can I measure the length of the RTB.rtf, in inches, as it will appear on the printer?

How can I set the width of a form in inches (or cm) instead of pixels?
I want to print the form, so it needs to always be the same dimensions (4" by 6"). I saw some examples for previous versions of VB, but nothing that works in VB10.

I need help creating a application that converts inches to feet and vice versa, this problem comes based off of this application I had to create to convert Fahrenheit to Celsius and vice versa--below is the first application. I get the basic idea of how to start, but Im having trouble with what I should put to start the conversion, what variable? Everything I'm putting in is coming up as error.
Option Strict On
Option Explicit On
Module TemperatureConverter

I am attempting to make a unit converter that converts between km, m, cm, miles, yards, feet, and inches. I have a textbox that is used to input the value to convert followed by a space and the units (i.e., 56 km) and a second textbox where the user types what unit they want to convert to (i.e., cm). When converting, the output will be displayed in the second textbox. (I know this is complicated, but this is the way it is to be done). I am doing this using sub and function procedures and If blocks and Select Case blocks (i.e., keeping it as simple as possible).

I would like to add an effect where a panel sweeps out of the way to make room for another panel. This is sort of like a sliding effect, and I think at one point in time this could be seen on Apple's website under their product pages. I came up with some code, but it isn't working.

When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).

I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

I'm working on a visual studio 2008 VB.Net project (.net framework 2.0), and am having some trouble with the Panel control using a fixedsingle border. As a small example of the problem, suppose I have one Panel2 contained inside of Panel1. If the Left position of panel2 is set to 0 (meaning it's border is up against the left edge of Panel1), the left border will show as bold, and slightly indented.

What I'd like to see is just a single line, not bold or indented, where the two panels borders are equal.Is there a property or custom paint technique I could use to achieve this behavior?

This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.

i`m trying to find in cm or mm the area of a frame (capture image).The picturebox has dimensions height:456 and width:553 PIXELS.So the total number of pixels are 456 x 553 = 252,168
If i compare image 1 with image 2 i can locate and draw a rectangle around that area of pixels that are different.i can get the width and the height of this rectangle in PIXELS.e.g Height:49 Width:33 PIXELS
How can i covert these into cm or mm. What i need to know for the conversion?
I know dpi: dots per inch but what`s the value for my rectangle?

I would like to believe that this code will display a horizontal line halfway across the PictureBox pbxData. In fact, what it does is create the BitMap and then blow up with a memory violation when trying to copy the BitMap into the PictureBox. The code that alters the array is commented out because I don't know how to address the elements of the array.
how to make this into useful code?
