I created a address book and I've noticed that it is very slow! I mean even when the database is empty the program takes a while to open. When you add pictures, it is even slower. I know it is probably because it is just using the picture you select (no matter waht size it is) and resizing (stretch) to make it fit in the picturebox I have. Now is there a way to speed the whole program up? Or is there a way to have a loading screen appear and preload the database and pictures (something that specifies what it is current loading). I would rather just speed up the database. If you know of an article I could read that would help me with this, or maybe if it is easy to just tell me then i would appreciate it!

Hello, I want to create a method for encrypting HTML code (may be Javascript based encryption). Can you give me any suggession or guideline ? Any free algorithm available for this ? or any .NET Class library ?
Example : my method can be like this,
string getEncryptedHTML(string plainHTML)
and it would return code like this :
<script language=javascript>s="a3Ca73~70B61B6EF20c6Fa6Ec63D6Fa6ED74a65~78a74B6D-65c6E.75c3DF22~72.65c74a75c72D6EB20~66B61D6Ca73~65B3B.22-20D6F~6E~64

Hi,
thanks for your help. Actually the links you provided gives me the idea about Encryption and Decryption. That means, I can encrypt a text but I need C# Again to decrypt the text. But my intention is to generate Encrypted HTML Text as a Javascript which will be decoded and displayed by Internet Explorer and other browsers.
|
|
|
|
|
It is a wasted effort. The code to decrypt would reside in the Javascript which would be easily stealable allowing a proficient user to steal the code anyway. The best bet is to use Ajax to populate the DOM which makes it more difficult to view the full source since many browser may not show the full source after a DOM operation, at least not yet.

Hello. I know I shouldn't come for such a simple problem, but I don't understand how to load an image. It was easy XNA, but regulaly is ...hard? I have an image file in the solution explorer under folders "Content" and "Sprites". Say the image is myImage. Whenever I declare a bitmap and then try to load in the public Form1 method, it always gives me an error. How do I load this image. (Does it matter the type of file?) Thanks in advance.

MasterSharp,
Is this image static?, eg do you ever need to change it?
If not, just use a picture box and load the image that way.
Also, Whats the error?
Regards,
Gareth

It's not static, but I don't really intend to change it. Do I have to use a picturebox? Can I just load it anywhere (I have multiple images with the for loop later...)

You load an image file using Image.FromFile() or Image.FromStream().
The former locks the file until the image gets disposed of.
You can also embed an image as a resource, and load it from there when needed.

What error? Please try to provide good information if you want to get good replies.
use a try-catch construct, catch the Exception, and look at Exception.ToString().
It will show a message, extra details, and a stack traceback. The first class.method
with a linenumber is the source line you should look at.
I hope you told Visual Editor to always display line numbers? (menu Tools/Options/
TextEditor...).

I know ehere it is. It's when I set the Bitmap previously declared to be a new Bitmap with a file extension. The error: ArgumentException was unhandled. Parameter is not valid.

MasterSharp wrote: a new Bitmap with a file extension
there is no such thing as a bitmap with a file extension, only files have an extension.
I'm guessing you are doing something like new Bitmap(filespec+".JPG")
and it throws the ArgumentException, so you must:
1. look at the exact value of the parameter you have there; is it a valid path?
2. if relative path is used, is the current directory at that point what you expect?
3. check that file exists
4. check that file contains a valid image (does it show a thumbnail in Windows Explorer).

Do I need te file extension or not? (jpg, png ... ?)
- I love D-flat!

This is it:
Btimap myBitmap;<br />
<br />
public Form1<br />
{<br />
<br />
myBitmap = new Bitmap("Content/Sprites/myImage.jpg");<br />
<br />
}
It doesn't work, when the file is under those folders in the explorer, WITH that name.

That is not the correct path. When visual studio builds it places your executable in the bin directory. ../../Content/Sprites/myImage.jpg might work but the easiest thing to do is change your project settings to move the images to the bin directory on compile.
However, I usually set the options to embed in the assemble and the use the GetManifestResourceStream method from the Assembly class to retrieve the streams at runtime.

So the suspicious things are under my earlier points
1. are slashes valid folder separators on your system?
2. this is a relative path, is curdir what you think it is?

A file extension is not mandatory; AFAIK GDI+ recognizes the image formats it supports
without needing the extension for that, so the only thing that matters is the filespec
correctly points to an existing and valid file.

Hi,
I am trying to deploy an application accompanied by a .chm help file. The file is referenced in the app by a helpProvider object that has a directory path property for the .chm.
Publishing the app is straight forward using the 'Click Once' publish wizard provided with 2005 Express. Unfortunately, when installed on the target computer, the app will only link to the .chm file if it has been placed (manually) in a directory that has exactly the same path as it had on the developer computer. The publish wizard seems to ignore the presence of the .chm file completely.
How do I publish the app so that the .chm file is included with it and installed automatically on the target computer?
A related 'problem' is that I cannot find the app on the target after it has been installed; the 'Program Files' directory does not appear to be used. Where does the app reside when it is installed on the target?
Thanks in advance JR.

Third party providers publish web services that you can call on a per use basis I believe.

Hi all
I want to set the items of a context menu at runtime, but there is no public constructor for the ToolStripItem class.
How should I achieve that?
