problem with drawstring and font "Microsoft Sans Serif" - C# Discussion Boards

WeifenLuos DockManager Question

29-Jun-04 5:29

What StringFormat are you actually using? Your sample code above uses new StringFormat with no parens, so that can't be it (perhaps you just forgot them and didn't copy and paste or anything). You might try using a typographic format, like the static StringFormat.GenericTypographic property, instead of just new'ing up a StringFormat.

A quick search on Google yields no known bugs using "Microsoft Sans Serif" and Graphics.DrawString.

Hi there!

A question for all folks that are using WeifenLuos DockManager (which I have to shortly intend is great!):

I've got two panes in my application. One is docked at the left and one has the state DockState.Document. I've got a couple of different DockContent derived Forms in this DocumentPanel. Depending on the users selection, I hide or show some of them using the appropriate functions Hide() and Show() of the DockContent deriatives.

Problem I'm having is that the documentPane (and it's Content windows) start flickering crazily. I've tried to ResumeLayout() and SuspendLayout() do supress layouting but it won't help. Goal is to supress any repainting until I'm set. Any ideas?

Thanks in advance!

Matthias

If eell I ,nust draw to your atenttion to het fakt that I can splel perfrectly well - i;ts my typeying that sukcs.

The best place for this question is on the discussion board under Weifen Luo's article, here[^]. He keeps it up to date and is the best person to ask about issues like this. It's also possible that it's a known bug and he just doesn't have a fix for it yet.

hi, i have a counter that counts down from 5 minutes. i have 2 separate displays: 1. minute display(which counts down every 60 seconds), 2. seconds display(which counts down from a minute i.e. 00, 59, 58 ....). what i cant figure out is how to make the second counter to restart at 00 after a minute has gone by. can anyone help me? thanks.

Sincerely,

Why do you need two counters?

Why not just have one counter counting the seconds?

Assuming your counter variable is called counter, each time the timer fires you increment it. To get the seconds and minutes try:

int seconds = counter % 60;
int minutes = counter / 60;

code with a foxpro database

i have a custome encrypt program for a foxpro database i have so i converted the program to csharp it encrypts data to and from a table but when i encrypt it using csharp i can't decrypt it because the charter maping in csharp is diffrent i think because i can encrypt the letter "a" using my method but i can't read it from the table in its encrypted form and turn it back into a "a" so can somebody help me

here is a copy of a method that dose basicly the same thing as the encrypt program i am trying to use the idea is the same and i can't change it because we have hundreds of programs that use this method to encrypt and decrypt data in these tables

public string encrypt(char[] txt)
{
int length=txt.Length;
int char_num;
StringBuilder result=new StringBuilder();
char[] out_array=new char[length];
double x,y,num;

for(char_num=1; char_num<=length; char_num++)
{
x=(double) txt[char_num-1];
y=0;
for(double bit=7;bit>=0;bit--)
{

num=(int) Math.Pow(2,bit)-1;
if(x > num)
{
num= Math.Pow(2,bit);
x=x-num;
num= Math.Pow(2,7-bit);
y=y+(num);
}

}

out_array[length-char_num]=(char) y;

}
for(char_num=0; char_num

Why can't you? An array of characters is an array of characters. Taking away the storage of a character array in memory, every language pretty much treats an array of characters the same.

Apparently, you store this in a table field as a sequence of characters, so that's what you get back, correct? So why can't you decrypt this? You're using a two-way hash (not very good encryption at all, but perhaps good enough for your requirements) so if you apply the hash algorithm in reverse on the ciphertext you end up with your plaintext.

If you're having problems with the decrypt method, I suggest you post it here.

Also, I noticed you have this declared as an instance method. Encrypt and Decrypt (notice the casing, too, which is consistent with the recommended .NET naming conventions) would probably work better as statics. I mean, unless you're encapsulating functionality into the containing class, these two methods are really more procedural. Just a suggestion.

that is just a quit encrypt method i wrote to post on this web site and i know there are better ways to encrypt but this was written in foxpro 2.0 for dos and there are still about 500 programs that use it in my company just have not got around to changing it but i can use this program to encrypt text from a text box and put it back in the textbox and when i run it again it decrypts but as soon as i store it to a table it changes ther charter set to where i can't decrypt it

on and that encrypt method is my decrypt method too its just for testing

ok let me explain what i tried i encrypted my name "chad" to a textbox and i cut it from the textbox and pasted it in a foxpro table after i pasted it there i cut it again from the foxpro table and pasted it back to a csharp from and tryied to decrypted it and could not and just to make sure i did not do anything wrong i also copy there encrypted text from the csharp form and trying to decrypted it and it works fine

as soon as i past the encrypted text into foxpro it changes the charters and it only seems to change charter from 128 and above can you help me fix this

Now that's handy to know. The text encoding for that field in FoxPro is incorrect. .NET stores and operates on Unicode text natively. What FoxPro has defined for that field is ASCII, which is only characters 127 and below. A codepage (and different regions, countries, and makers have their own) defines the rest of the characters.

What you need to do is change the encoding of that field to UTF8 (like ASCII, but allows for 2-byte characters above 127, making it a good replacement for ASCII on older systems in order to support Unicode as well) or to Unicode (either UCS2 or UCS4).

The other option is to base64-encode the text so that only ASCII characters are used (thus not requiring a change in the FoxPro database). You can do this simply over the byte[] that represents the ciphertext (which is binary anyway - not text!) using Convert.ToBase64String and Convert.FromBase64String. Base64 is the common encoding used for ciphertext (encrypted text) because it's fairly compact and can easily represents arbitrary bytes.

ok foxpros codepage is 1252 and it dose allow for characters above 128 it is double-byte characters
what else could i try
