Hi,
first of all I don't have any experience printing RTB content. But looking at your code
I can see you only take its (Selected)Text, i.e. the string representing its content,
ignoring all formatting (font selection, colors, bullets, ...). This does not look right.
May I suggest you search CP (or Google) for "RichTextBox print".

That is not very informative, you don't tell us what you did and tried, and what parts
did or did not work.
Did you search CodeProject articles? Here is one for starters[^].

You can use SqlDataAdapter class to retrieve data into dataset using stored procedures

Use a SQLDataAdapter object, and use Fill() method to fill the dataset.

Hi,
If i have a 100*100 array of values (say 0 is black and 255 white), how do I display it as in image on a picture box ?

Create a Bitmap object and use the SetPixel method to set the color of each pixel.
If you need extra speed, you can use the LockBits and UnlockBits methods to access the pixel data more directly.
Experience is the sum of all the mistakes you have done.

Append a bitmap header to a memory stream and then copy your array to the stream. Then create a new bitmap using the stream constructor. That will be the fastest way. See wikipedia for the format definition.

I am currently using the HTTPWebRequest class. I need to add the following to the request line:
POST /Search HTTP/1.1
It is simple to get 'POST HTTP/1.1' but i am having difficulty adding the additional string.
I cannot seem to get the '/Search' inserted in the request line. I understand HTTP 1.1 and the VERBS allowed as part of a request.
The 'method' property is used to set the VERB. Adding anything other than a single string throws a null reference exception. I have seen extra information appended to the method many times in the past so not too sure why this is so problematic.
I initially thought of overriding the HTTPWebRequest but as it is created from calling Create() on the WebRequest, this doesn't appear possible.
Thanks in advance.

As far as I know, you only have access to the Headers collection on the HttpWebRequest. You will probably need to write your own class for this functionality.
Luckily, you can use this post as a basis for getting that done. http://www.thescripts.com/forum/thread343158.html[^]
Good luck.

Hi Mike,
thanks for the post. I did something very similar already as a back up to the problem, using the TCPClient and NetworkStream. Created an additional HttpProtocol class and added all the members that might be needed. provided an override of ToString with booleans against each of the properties as to whether to include them in the ToString. Feels so cludgy though. plus it's a real pain interrogating the response headers and content. as it just comes back as a byte array.
still think there must be a better way.
thanks.
Carl

Hi!
I have 2 buttons in my form and array objects of picturebox.
when button1 is clicked. One Picture box is created. Then i move it (picturebox1)to a desire place.
I clicked button1 again and the second picturebox (picturebox2) is also created and i move it to a place that i want.
The problem is when i click the picturebox1 after the picturebox2 is created and moved. The picturebox2 moves automatically and disappears quickly. I don't know why and how to fix it.
Best regard!

We know why - there's bugs in your code. Can't really offer much more help than that, without seeing the code.

You should use a list, this will break after 5 items.
If you debug, is count 0 or 1 the second time ? It looks like it should be 1, but it seems likely it's not.

I can't debug because when i just move mouse on the picturebox, click event is not excuted but the mouse move event is excuted firstly. So the mouse move event is always happened while i can't reach the mouse click event.
By the way, count is always increased after clicking button1.
Please tell me how to correct the problem.
Thanks for replying.

Okay, first off, don't use myPic[count-1] to access the control you want tp drag, you have the object 'sender' which is the control that was actually clicked, so if you use:
PictureBox temp = sender as PictureBox;
temp.Location.X = ...
temp.Location.Y =
...
Then you will always drag the picture box that you actually clicked.
Infact, if you add another picturebox like, currentPicBox or something and use that to find out which picbox was clicked. So, in the MouseDown event:
currentPicBox = sender as PictureBox;
and in the mouse move event:
currentPicBox.Location.X
...

It works.
But when i clicked currentPicBox and move, there is more than 1 currentPicBox moving. That seems it appears and disappears, appears and disappears... until MouseUp event happens. So how to resolve?
Thanks for replying.

I have the following scenario:
An application is using async. keys to verify itself to other apps. I've put the key in the key container with the following code:
CspParameters csp = new CspParameters();<br />
csp.KeyContainerName = "MyApplication"; <br />
RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(csp);
The problem is that the (untrusted) user can make another application and easily get the key.
Is there any way to make a key accessible to my application only? The application could e.g. be identified by Strong Naming it...
PS: I am aware that one could run the app as a special user, and let that user have rights, but this application will launch other apps, and those other apps should preferably be run as the logged in user)

The only way this would be truely possible is if a web service (or another type of service) encrypts the key before saving to disk. The user would have no access to the web service, and therefore could not get the password used to encrypt the file. You would then need to use the same service to decrypt the file before using.
This service could be a simply Windows Service running on the same box as your application. You could then set the service to run as a user with priviliges (for example, to a directory) that your real user doesn't have.
Basically, if your application (running as the user) can encrypt/decrypt the file then the user would be able to do it without your application. Some developers embed a password in their application binaries and use that for encryption and decryption. A technical user could extract the password from your binary (regardless of whether it's in .Net).
You can use impersonation[^] to launch applications as different users.
Take care,
Tom

Thank you very much for your reply!
I have one follow-up question:
If I create a Windows Service, running as a privileged user, I agree that the key (on disk) is safe. But when my application asks the service for the key, how can the Windows Service know that it gives the (unencrypted) key to the correct program? Is there a secure way for a WinForm program to communicate with a service?

The idea is that you pass the encrypted data to the windows service and it would decrypt it for you (and encrypt). It would not provide the password to your application.
As far as whether it's talking to the correct program. The user would have to have enough restrictions that they cannot run another application that can talk to your service.
The best way to think of it is, anything your application can do, another application could do. So you need to restrict the users right enough that they can't use "another application".
Take care,
Tom
