As the heading suggests, I'm trying to give the user the option to choose an image using the FileUpload control and after hitting the update button, display it in the Image control, existing inside a Panel control.
So far I've gotten here. This is my form.
And this is my code.
I let the highlighted code stay inside PageLoad function just for testing. I know it should be inside the Button's event handler.
Also, can someone explain me why the above fails to display the image even after hardcoding an absolute URL for Image.ImageUrl property. It worked when I referenced it just by giving the file name cake.png and putting the file inside the website folder. But I want to reference absolute URLs.
Any and all help is appreciated. Thanks.
You are creating a web application, which can be available on internet and can be accessible throughout the globe. In your example, which is not working, you are referencing a image file from local file system from your own computer, inside a web application. Your Web application is running under its own process and under its own account/user(IUSR in case of IIS) and your local system is running under a different process. so the two can't talk to each other like that.

I am trying to SendKeys to a user control which has a web browser inside. I haven't found a decent solution apart from copying the data to a clipboard and pasting it inside the control with a button. Can anyone help on this? I don't currently have any code for this yet.
I've tried:
this.webBrowser1.Focus();
SendKeys.SendWait("example");
However, I don't know how to position the code to target the user controls and web browser in the fashion I want it.
Does anybody know how to do this?
If this is a WinForm application and it has a browser control it must have a property for src or href to hold the url of a page you can make use of that.
But you can also use SendKeys to copy/paste content to/from clipboard:
SendKeys.SendWait("^(c)");
will copy the selected to clipboard and
SendKeys.SendWait("^(v)");
will paste it for you in the current cursor position.
I haven't looked into it very much but am struggling to find relevant information on the topic. I basically want to create a browser that applies a filter to a webpage by changing colors in a webpage. My guess is that I will have to change the html once loaded or something, would this work? Do I have other options?
PS. I don't just want to make every color darker, I would more like to invert the colors.
Edit:
If any you were wondering, I am talking about the XAML browser component that can be used in a Windows Phone application.
I think the simplest way to do that is to inject some Javascript into your page once it has loaded.
To do that, you need to set the IsScriptEnabled to true on your WebBrowser control and then subscribe to the Navigated event.
When that event occurs you can inject some JS codeby using the WebBrowser.InvokeScript method.
Here is an example of JS code that darken the page : JavaScript: Invert color on all elements of a page
If you are talking about in a PC internet browser, you can find an add-on to execute Javascript automatically, such as Greasemonkey for Firefox. If you are talking about Windows Phone's Internet Explorer, I don't really know what you could do there, as I don't think they allow add-ons.
In a traditional web browser (Chrome, IE, etc.), I can grab an image and drag it somewhere else, and depending on the application, I can drop the image and something will happen: it will be displayed, opened, saved, etc.
In the application I'm working on, I've added event handlers and code to download and display an image if you drag and drop it onto one of the PictureBoxes on the form. Works great, no problems with that.
For whatever reason, if I load a page in a WebBrowser control, I can't drag images from the page that's loaded. At first I thought maybe I had changed a property of the control that was disabling this functionality, but I created a brand new project with nothing but a WebBrowser on the form and pointed it to a few different pages with images. Even pointing it to a local file with just an img tag in it, I cannot get it to drag images out of the displayed pages. If I select text, I'm able to drag that text out, but no images.
Is there a property I'm missing that I need to set to enable this functionality?
Running in .NET 4 on Win 7 x86 with IE 10 and the registry key to cause the WebBrowser class to use the IE 10 engine. (also tried disabling that and going back to the default IE 7 engine)
Still haven't found an answer to the actual issue, but I found that wrapping my img tag with an anchor with href set to the image path, I can now drag and drop that anchor in the normal way. Drop event handler still manages to get a file path that works, and I have no problem setting the WebBrowser control's AllowNavigation to false. Couple CSS changes and I'm done.
I am using some web user controls on a website I am creating, but the problem is that sometimes visual studio cant load the control because he (my guess) needs a namespace imported where the web user control is located in. To make things more clear here's the line of code I am reusing to make objects of the web user control.
Criterialijn criterialijn = (Criterialijn)LoadControl("~/Criterialijn.ascx");
When I first execute this, he does not know about what object I am talking about, but when I drag and drop the .ascx control into the app_code folder and drag and drop it back out, everything is fine : he lets me load the web user controls and knows about what object I am talking about. Now this is a kind of retarded solution so my question is how do I fix the web user control so that he immediately knows about what object I am talking about when I create it?
This is how I do using a placeholder. Hope it helps.
Criterialijn criterialijn = (Criterialijn)LoadControl("~/Criterialijn.ascx");
PlaceHolder1.Controls.Add(criterialijn);
I would like to integrate moneybookers payment-gateway into a WPF-application. Accroding to the official gateway manual I need to redirect the user to the moneybookers payment-page and submit some fields posted within an html-form.
Has anyone an idea how I could solve this task?
Best regards!
Yes, all you need to do is:
Include a Frame control in your WPF application.
Include a .html file in your WPF application that contains a element with the appropriate data and some JavaScript to automatically post the form when the page is loaded.
When it is time for payment, have your display the Frame control and set its Url to the relative path of the .html file.
When the user is done paying you can give them a button to close the Frame yourself, or you can subscribe to the Navigated event on the Frame and when the payment processor causes them to navigate back to your fake HTML you can automatically close the Frame and use your own WPF UI to tell them "congratulations, thanks for paying".
