Hello,
I'm trying to convert txt files containing some html tags and text in cyrillic to html. What I do is add the and tags at the beginning and at the end. Also I'm using regular expressions to replace a image name with tag to actually show the picture. The problem is that when I read the file with ReadToEnd() the cyrillic text is missing. If I read the file as byte array I don't know how to use regular expressions to insert the pictures. Could you please help with some advices?
Thanks

Without seeing some of your code - specially the code to construct the reader - it's difficult to say for sure what the problem is.
You do need to set the encoding of the TextReader, though:
Encoding enc = Encoding.GetEncoding(1251);
using (TextReader reader = new StreamReader(path, enc, true))
{
string content = reader.ReadToEnd();
}If you're having trouble entering Cyrillic text in your regular expressions, use the \uXXXX notation in C# to enter the Unicode code point, like \u0041 is "A".

It is said that an assembly with a strong name (i.e., digitally signed) is safe from hacking in as much as its integrity and identity are guaranteed. This means that nobody can replace some code in your assembly with a strong name, as in that case it won't run.
My question is - What if somebody tries to decompile such an assembly (with a strong name) and then after making some changes in the code, again recompile it? Is there anything in the .NET which prevents decompilation of an assembly with a strong name? Moreover, if such an assembly with a strong name can be decompiled and then recompiled again (after making some changes), then where is the security from hacking of the code? In such a situation, will it not mean that a strong naming also does not ensure full safety?
Can somebody throw some light on this issue?
Thanks in advance.

I'm afraid, the term "is safe from hacking" is plain wrong.
You can easily decompile a strong name assembly and modify it.
When you just do this and recompile, this won't work, though.
But when you remove the strong name signature from the assembly while modifying it, the assembly can be compiled and will be usable, although you will see that it's no longer signed by the original source.
I found an article on this topic a while ago, but don't have the URL ready right now, sorry.
When I find it I'll post it.
Regards,
mav

I found the article. It was - of course - here on CP:

strong name and digitally signed not used to prevent decomppiletion they use to prove that this assembly from you?
no thing prevent someone to decompile your code?
because as you know .net programm not compile directly to machine code the compile to clr so if you want to prevent
decompilation you can use Ngen.exe which will compile your application to machine code -even this will not prevent disassemble your code -but you loos some benefits
so waht? there are some tools that make decompilation process more harder (obfuscator) by renaming namespace , clasess... etc and do other things like try to make decompier crach

I had a hard time trying to find a simple way to allow a user to remove the selection of multiple items in a listbox, so after a half hour of experimenting I found a surprisingly simple solution:
<br />
do<br />
{<br />
listBoxName.Items.RemoveAt(listBoxName.SelectedIndices[0]);<br />
}<br />
while (listBoxName.SelectedIndices.Count > 0);
We are allowed to always remove the "0th" selection because we are removing as we go, and so the "next" item will become the "0th" item when the current one is deleted. Then in the Do-While loop we just continue until we run out of selected items. Make sense? It seems relatively simple, but I wasn't able to find any similar help so i figured id post here in case someone else runs into the same problem.

you can use triggers so when event happen do somthing
like write what happend to file check this file from your
programm in interval time
another thing look at documentation see if you can consume triggers directly from your program

i am trying to get a few dynamic image forms/pages/whatever you want to call them on my site, i made a form that simply writes the binary stream for an image object into the response stream and this works, but i need to get this to function while the file is .jpg and not .aspx
does anyone know how to make IIS handle .jpgs as .net apps?
|
|
|
|
|
In IIS manager, open the properties for the site, go to the Home Directory tab and click Configuration. Look att the entry for .aspx files, and add one with the same settings for .jpg files.

b { font-weight: normal; }

i tried this and it doesn't seem to be working. i think it has something to do with content-type. in the code-behind i have to specify the content type to be image/jpg (or image/png) so that browsers like mozilla recognize it, is there a way to specify content type in the page directive?
|
|
|
|
|
Standard question #1:
What do you mean by "not working"?
---
b { font-weight: normal; }
|
|
|
|
|
Firefox: The image “http://localhost/DynamicImage/image.png” cannot be displayed, because it contains errors.
Iexplore: <%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" Inherits="DynamicImage.WebForm1" %>
http://kbirger.no-ip.org/kir/image.png
http://kbirger.no-ip.org/kir/WebForm1.aspx
^ that's the working version
|
|
|
|
|
That is because the asp.net code is not executed at all. What is sent to the browser is only the contents of the file, unaltered.
Have you registered then .png file type to be handled by asp.net?
---
b { font-weight: normal; }
|
|
|
|
|
i registered both .jpg and .png the same as .aspx in the method mentioned above, but it still does not respond.
the page itself returns an image and only an image (if you look at the source / hex) so i don't see what the problem is
|
|
|
|
|
The problem is that the code for the page is not executed at all, as the server does not recognise the files as being asp.net files.
Check the settings again.

b { font-weight: normal; }

At the moment I have to reinstall something on each computer, so I'll be configuring it from the start.
All i have to do is go into the script configuration and change my image files to have the same settings as aspx files? i don't have to change the mime types?
|
|
|
|
|

that didn't seem to do anything. (i tried changing it between image/png and text/html)

Hello,
I wrote a method to convert image's color table.
public class convert
{
public static Bitmap bmp_convert(System.Drawing.Image pic)
{
Bitmap b = new Bitmap (pic);
BitmapData bmData =b.LockBits(new Rectangle(0, 0, b.Width, b.Height), ImageLockMode.ReadWrite, PixelFormat.Format16bppArgb1555);
b.UnlockBits(bmData);
return b;
}
}
unfortunately, I can't convert my image to Format8bppIndexed (or any indexed format) while to the other formats I can...(like: Format16bppArgb1555),why? and how can I fix it?

How would I go about embedding a combobox in a cell of a listview when set to details view? I've looked at this article ListViewEmbeddedControls[^] but unfortuatly the combobox height is bigger than the row height. Can I maybe overwrite the row height before drawing?
Thanks,
Rob Tomson

Hi:
I'm using a datagrid in my project to display data from a dataset. The dataset is bound to the datagrid and several textBoxes. //this.datagrid.DataSource = this.dataSet; this.tbFamily.DataBindings.Add("Text",this.dataSet,"Table.Family");
I assigned the bound dataset to a bindingManager because I need to show the currently selected data from the datagrid in textboxes. //BindingManagerBase manager = this.BindingContext[this.ds, "Table"];
I use //this.manager.Position = this.datagrid.CurrentRowIndex; within a CurrentCellChanged event to control the position of the manager each time the user selects a new row in the datagrid..
This works fine until the datagrid is sorted by clicking on the Columnheader because the "sorted" data doesn't seem to "remember" its index prior to sorting...thereby displaying the wrong data in the textboxes
Can someone please show some code that I can use to make sure that sorted data remembers the pre-sorted index?
Thank you.

If you add this code to your program, the datagrid will be in a sorted format
CurrencyManager cm = (CurrencyManager)this.BindingContext[this.dataSet, "Table.Family"];
DataView dv = (DataView)cm.List;
dv.Sort = "xxx"; // the column you want to sorted.
Then you can use
BindingManagerBase manager = this.BindingContext[this.dataSet, "Table.Family"];
DataRowView view = (DataRowView) manager.Current;
DataRow row = view.Row;
to get the row you want.
Don't try to use the index, because it's not accurate if you delete a record from the datagrid.
Hope this helps
