Hello,

I want to make an app that compares an image with other images stored in a folder.
More exactly the main image is an multiple choice test solved correctly and the images stored in the X folder are the tests solved by students.

I want the app to be very flexible so i was thinking at defining an area that corresponds to the correct answer and so on for every question and save the coordinates of the area in an text or XML file. Then i can import the saved areas and assign them to every solved paper and check if the number of pixels in the correctly solved paper is (<, =) then the nr of pixels in the paper.

Can you suggest me some classes or anything that might be useful??
Thanks!

I will show you how to compare the image in C#. ( but the way you wanna use is very strange for me..)

Stream s1,s2;<br />
<br />
//You have to add the codes to read the image...<br />
<br />
            if (s1.Length != s2.Length)<br />
            {<br />
                return false;<br />
            }<br />
            s1.Position = s2.Position = 0;<br />
            for (int pos = 0; pos < s1.Length; pos++)<br />
            {<br />
                int byte1 = s1.ReadByte();<br />
                int byte2 = s2.ReadByte();<br />
                if (byte1 != byte2)<br />
                {<br />
                    return false;<br />
                }<br />
                if (byte1 < 0) break;<br />
            }<br />
            return true;<br />
<br />

hope it helps.

Thanks and Regards,

Code looks fine. Are adding any file extensions with the file name ? Try setting sfd.AddExtension = true;.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Hmm, odd. Are you sure you havn't set the BackgroundImage property of the picturebox by mistake?

Hi,

I want to create one MSI Package with following requirement

1)There should not be any entry in Add Remove entry, Control Panel

3) When MSI package is created, the EXE will reside in a subfolder named 'temp'.

This is very urgent requirement. Please suggest how to create MSI Package.

To do what? Close the web browser, or end the users session? If it's the web browser, use window.close()* in the client javascript. If the session, the code behind should use Session.Abandon();.

*If the window hasn't been opened from another browser, it won't close without prompting the user.

Hi,

I have created two projects, One is an EXE and other one is DLL. The DLL is referanced by EXE Project. The Exe & Dll Are working fine.

I Need to hide code of dll. So I use .NET Obfuscator Community edition (Which comes with VS 2005) to Obfuscat dll. It was done successfully.

The problem is Now when I am executing Exe it generate errors about missing Classes (Those classes are Withing DLL)

What can I do for this scenario ? Is it the nature of Community Edition ?

Please help me to solve this problem.

Thanks

Dinesh

Are you using reflection to load those classes? I don't think the community edition is any good for this type of situation.

Take a look at the ObfuscationAttribute in the System.Reflection namespace.

Putting Letters Into a c# 2.0 winforms app

Hi all,

I was wondering if anyone could give me a push in the right direction Smile | :)

I am writing an application that needs to show letters. These Letters need to be updated with information about our customers from our database.
I have considered using RTF and regular expressions to find the positions to place the new data. I found a control TxTextControl but am worried that this may get a bit messy! Both in the database (storing huge RTF) and in the app.

Does anyone have any ideas on the direction I should take ??

Thanks
John

Well, as what you've described sounds exactly like mail merge, have you considered using Word? If you've got Word 2007 installed, you could even fill the information in by directly targeting the Word XML.

Not without using a word viewer. As a quick thought though, have you considered using WPF and its support for documents? It has an inbuilt document viewer that allows you to view XPS documents. Office 2007 does allow you to save documents as XPS, so you could possibly use automation in office to generate the documents and then open them up in the DocumentViewer control.

Thanks for the replies,

I need it embedded in the app so that I can put it out into the business and they can build up the letter by making selections e.g. a button that when clicked adds a disclaimer to the letter... these button clicks would then need to search a template document for a place holder and put in the relevant text. the docx seems to be able to do this but i need it so that the user can only manipulate the document in the app.

Any ideas Smile | :)

Well - the XPS solution would seem to be a goer for you. It's not trivial, but it will result in a document that you can manipulate through your code, and which renders out like a PDF. This[^] link should help.

Use the forms Resize event and the FormWindowState enum to determine the
forms current state.

private void frmMain_Resize(object sender, EventArgs e)
{
    if (System.Windows.Forms.FormWindowState.Minimized == FormWindowState.Minimized)
        this.Hide();
}
