I have a picturebox with an image in it. I want to 'select' a section of this image (like standard selection tools in other image editors) and place it in another picturebox... The piece I want to select is a square and I have the coordinates.

View 5 RepliesIs there any easy way to check if a selection made by a user from the browser is an image type and not any other file type. I could check for extension types i.e. bmp, jpg etc but what I would like to know is whether there is a generic term.
View 4 RepliesI'm working on a WYSIWYG Blog Editor, I'm having an issue with my text selection. I've added a couple of graphics to illustrate. My code is selecting the text and putting it back into the textbox, but it's adding extra text. I can't quite figure out how to get it to select the intended text and manipulate it correctly (make it Bold or Italic and so on,) and then show the text in the two windows (one is the Textbox and the other is a webtext box) correctly.
Below is my code and my 2 graphics.
Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
boldstart = "[ b ]" 'variables to hold formatting
boldend = "[ /b ]"
wboldstart = "<b>"
wboldend = "</b>"
clearrtf = ""
[CODE]............
Every thing works up to the point when I try to manipulate the text, it then puts more text in. I have been trying to find info on how to clear the text box and then re-insert the text with the text formatting. Side note in my graphics is a small graphic that is just there as a marker for me, it has no affect on the actual program.
is there a section on how to add controls, Ie like in fire fox Tools/Options

View 1 RepliesFor some reason I could never get over the look of my application, and the Microsoft controls together. Just never looked right. Nor were the controls exactly what I needed. By creating controls I can pretty much custom fit them for my application, and I love it.My question is with drawing these controls. I have 12 of them now in my current project, so I would like to make them all as efficient as possible. The biggest set back to most of them is the drawing can be a little extensive, or at least to a point where they could be more efficient. At the moment, under each paint event I have the brushes created by using blocks and then the drawing happens within them(I create all brushes first, then do the drawing, vice versa with disposing them). My question however came up when I was creating my most recent control, a SimpleList.
I experimented to see(though I'm not sure how exactly to track performance) but instead of recreating the brushes and pens etc in the paint event, I put them at the top so they're only made once, and destroyed once, rather being made and destroyed every time my control paints. My common sense tells me this is a better way of going about this but my experience can't back that up. is this the way I should be going about user drawn controls?, is there any limitations to this?(like would it be okay if I only had a limited number of brushes etc) and is the performance even that greatly impacted by making these changes that it's worth my while?
in my old projects when i had create a project it comes with the crystal report's tools in the toolbox .
but now in the 2010 when i Create a new project a crystal report tools doesn't come with in toolbox , With science there is crystal report in my pc .
all of all how can I add a crystal report tools to the toolbox manually .
I usually use standard button and do the settings like causevalidation etc if required.
i decided to use toolstrip and inserted some buttons but end up that it doesn't do the validation for control and also doesn't call leave event of textbox control.
so my question is, anyway to use regular button functionality for toolstripbutton or there is a way to add regular button on toolstrip.

Im making a simple image editor and I added Zooming and Drawing with mouse position like a pencil. My problem is When I zoom the image and try to draw on it, everything becomes offset and the lines i drew are not even close to the mouse. Here is My code ( Just add a button1 and Picturebox1 with an image)
Public Class Form1
Dim pen1 As Pen
Dim x1, y1, x2, y2 As Integer
Dim gr As Graphics

I have a bundle of tiny pictureboxes on a form. The number is specified by the user, but it could be up to 100, or so. The user can select any set of these pictureboxes by a variety of means. I want to change the image to show the selection state of the pictureboxes, and I'm looking for the best way to do that. The pictureboxes each shows a bitmap. The brute force method would be to have a selected image and an unselected image and just swap them, but it seems like there ought to be a way to do something significant and reversible to the image, such as inverting the colors, that might be smaller that having a second copy of each image.

I am trying to add a TabPage containing a UserControl to a TabControl at runtime, because the number of TabPages to add are determined at runtime.
The UserControl (objDataInfo) is just two Textboxes, two labels and two Radiobuttons, nothing too exciting...
The TextBoxes have their Anchor properties set to Left, Up, Right so they scale with the width of the usercontrol.
The TabPages are added in the constructor of the form, which takes the number of tabpages to create (n) as an argument:
vb.net
Dim cList As List(Of objDataInfo)
Public Sub New(ByVal n As Integer)
[Code]....
So... How can I get the standard BackColor of a standard TabPage?
(I tried leaving out the usercontrol all-together, but the TabPage still has a gray background...)
I have a application which processes 1000's datas.. for each processing it needs to update gui and db and many variables in my application.

I want to be able to change an image depending on what is selected in the drop down box. I have this JS code to change the image. Simplified of course.
<script type="text/javascript">
function changeImage() {
var oDDL = document.all("ddlNAME");
var NAME= oDDL.options[oDDL.selectedIndex].text;
switch(NAME) {
[Code] .....
When I call this function I do it in my DDL implementation.
<asp:DropDownList ID="ddlNAME" runat="server" OnTextChanged="changeImage()" >
But for some reason the changeImage() is not firing. It is giving me an error saying
'changeImage' is not a member of 'ASP.default_aspx'
whats the quickest and least application hogging way to retrieve image from web and show in picturebox on listview selection event?
Heres the code i have already which produces app lag for abut 3-5 seconds per image loaded, i think as it stretches the image to fit into picturebox (which is needed)

If i wanted to crop an image in VB.net, how would I go about doing it? I am trying to let the user drag out the box they want (system.drawing.rectangle), and it will automatically remove the edges surrounding the box.
My first problem is primarily the fact that I cannot make the system.drawing.rectangle visible. It is not displaying at all, I am setting its location and height programmatically, but nothing is showing up. I know there is probably something fairly obvious I am missing...but I cannot seem to find it.
My larger issue, however, lies with the cropping itself. I cannot find any crop methods, at all. Is there a hidden one I am missing? Or must I code it myself? How would I go about doing this? It ought to be able to output to a bitmap image object.
