What I have: 1 OpenFileDialog, 1 PictureBox, 2 TextBox's This is what I got so far, but I'm just stuck on how to have the width of the image automatically detect and put the images width in pixels in TextBox1, and the height in TextBox2.

I use some code to successfully resize and save images - but I want to save the image to 800x800 px size on a canvas of 900x900px so it has a white border type thing around it.
View 8 RepliesI have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).
I am working with vb.net and want to increase the size of image when the cursor is over that image, but the image should come back to its original size when the cursor leaves that image area.I've used the following code to increase the size of image:[code]I've used the default size class but, it gives some different dimensions.by the code that brings the image into its original size that I've been declared into the picture box properties.
View 2 RepliesI am trying to split the image into 9 equal regions , and the below code does it well the problem is i want to get the selected image size and not picturebox sizeso what should i change to get the selected image size instead of picture box sizei dont want the picture box to grow in size with image because it will hide other buttons/textboxes etc
Dim xi As Integer = (PictureBox1.Image.Height)
Dim yi As Integer = PictureBox1.Image.Width
Dim px As Integer = xi / 3

View 5 RepliesI've finally cracked how to detect that Form1's size has changed?[code]Now I have another problem, my intention was to adjust the font sizes of some labels, buttons and textboxes to reflect the change in form1's size.I find that font size is Read only, so I thought OK then, I'll adjust the Bold: Wrong! bold is also Read only.Ideally I'd like to leave the bold on and adjust the character size.The controls all change size correctly within the minimum width and height restrictions of the form, but sadly, the larger some controls get their texts start to look like a pea on a drum.

If I re-size the form, the textbox inside should be re-sized to fit the form, NOT DOCK!
Anybody know a way to detect and set the form size in the child and MDIParent forms?
I'm having all kinds of problems from scroll bars popping up, to can't get the form to fill the parent. Pretty sure I have tried every possible combination in the forms properties 10 times.
I'm really getting tired of beating myself against this. Anybody seen a good tutorial on the finer points of MDIparent / MDI Child page size, etc.
how can I detect if press Enter in the Textbox Change event and not in Textbox Keypress?
View 3 RepliesI have a form which contains an Image control. What I am trying to do is find a way to adjust an image according to the size of the control and have the image look normal no matter how I adjust the Image control. I want the actual image to fill the Image control completely and not loose any integrity.
View 2 RepliesI'd like to set the form size to the size of a textbox. The size of the textbox can differ, as it is set to auto-size. However when I use this code, which should work (as far as I know) the form just goes to 0 height and 0 width:

I'm writing a Cleint/Host program that sends a image over tcp (from printscreen, not a file) to the host. Everything seems to work fine and the image is transmitted and displayed in a picturebox plus saved to a folder. The problem is when the printscreen is bigger than 176040 B. First the limit was 128000B but after setting the sendbuffersize and recivebuffersize to 1000kb the limit is 176040 B. Could it be a limit in the tcp protocol?

I am using a RichTextBox control on my form. I want a small code which can detect if any image has been inserted in the rtb or not. (IDE VS 2008)
For e.g. user can just type some text or insert image also (Ctrl + V). Now if we select an image then we can get the type but I want a code which scans contents of rtb and gives me a true if an image is inserted or false if there is none.
I already have the setting in Outlook to prevent automatic downloading of images but I still receive e-mail junk mail containing stationary. There is even a setting that prevents all images but that is the problem: It does it to ALL images.I would like to trap and move all messages with any kind of image in it and send it to a junk-mail folder. Someone told me that I might do it with a plug-in or an add-on and that it might be able to do this in VB.

View 1 RepliesI have a picturebox with a tiled background image (plane white bitmap), and an "image" resource centered in the middle of it, I would like to chance the size of this centered image within the picturebox.
I tried:
picScaledRepresentation.SizeMode = PictureBoxSizeMode.CenterImage
picScaledRepresentation.Size = New Size(Width, Height)
But this just changed the the size of the whole picturebox, rather than the image within it.
I'm currently working on a school project. And a part of the program is to 'change' the images. All images added are BMP-files. But the output has to be JPEG. Now there are 2 other problems:
- The width of the image should be between (70-165 ) Pixel and the height between (65-185 )Pixel
- The filesize of the image should be between (3-4 KB)
I know how to change the width/height, but it's hard to make the filesize between 3-4 KB.
The Textbox_TextChanged event fires when a key is pressed or when text is pasted while cursor is in a text box.
Is there an event that fires on Textbox1.text="NewText"? How do I detect this?My reason for doing this is I would like to reformat text property automatically on assignment rather than do something like textbox.text=myreformat("Newtext").I can put code in validating or validated event but then I'd have to force focus/lostfocus to trigger one of those events.

I am new to Visual Basic and i am using VS 2008. I have a form with multiple (7) text boxes. What i would like to accomplish is basically, when i click on textbox 1 a predefined message would load to label1 and when i click on textbox2 label1 would now displays a different pre-defined message and etc... I've tried using the "focus" parameter of the textbox but it doesn't work. So i am thinking of using the cursor as a way to solve my problem but i don't know how to work with it. I found a very similar thread titled " Detect when the cursor is in a textbox/typing in webbrowser?" on this forum but i don't think it applies to my situation.
