The length of an UTF8 string can be interpreted in two ways:
1. The number of bytes that the encoded data uses.
2. The number of character that the decoded data contains.
The Encoding class has the GetByteCount to calculate the first one, and GetCharCount to calculate the second one.

Hi. I'm trying to measure one line string with the space character at the end. For example "Testing string ".
The problem is that the size that I get is the same size measured without the space at the end. Anybody knows how to make MeasureString() take the space character at the end into consideration?

|
|
Make sure you pass StringFormat with MeasureTrainingSpaces:
StringFormat format = new StringFormat(StringFormatFlags.MeasureTrailingSpaces);
g.MeasureString(..., format);

Hi,

I would imagine you'd send keyboard messages to the window in question.

Use WS_EX_NOACTIVATE on the window styles, so the OSK won't gain any focus.

I've got some problems parsing strings and /* */ comments. Any help will be appreciated.
-----------------
// multyline comments
case '*': case '/': case '(': case ')': case '+': case '-': case '=': case '~': case '|': case ';': case '%': case '&': case '{': case '}': case ',': case '[': case ']': case '?': case ':': case '^': case '<': case '>': case '!': case '.':
substr += s[i];
i++;
{
if(i < s.Length && (substr == "/"))
{
if(i < s.Length && (s[i]== '*'))
{
do { substr += s[i];
i++;
}
while (i < s.Length && substr== "*/");
rTB2.Text += "Komentar - " + substr + "\n";
substr = "";
}
-----------------
case '"':
{
do
{
substr += s[i];
i++;
}
while (i < s.Length && s[i]!='"');
rTB2.Text += "Tekst - " + substr + "\n";
substr = "";

Why not just post your problem here? Few are going to take the time to download, unzip, and study your code on their spare time. Just post the problems you're havnig here and we can help you.
Also, if you code is in the C or C++ languages (guessing by your zip name), you're in the wrong forum.

I created a user control in C# that I'd like to display in IE. I also did create a virtual directory on my local host. It works fine on one machine, but I can't get the control to show up on 3 other machines. They just show a placeholder box for the control.
Here is html that I am using:
<object id="MyUserCtrl"
="" classid="http://localhost/MyCtrl/MyCtrl.dll#MyCtrl.UserControl1" height="500" width="500" viewastext="">
I think this might have something to do with my IIS settings?
Please help.

Do these other machines have the .NET Framework installed? They'll need it to run your control.
Also, is .NET Framework and IE security setup properly to allow code to be executed from a network source?

Well, the other machines will need the .NET framework on their machines. Also, if your control is doing anything that requires elevated security permissions, you'll need to grant that assembly higher privileges.

Try adding your website to the target machine's trusted sites list in Internet Explorer.
One thing you might want to try is just a simple "hello world" inside IE to see if the users can even run that. If they can't, we know it has nothing to do with your code and its security permission requirements.

the fact that I can run it on one of the machines tells me that the app itself is ok. I even did not have to add my site to the trusted sites there. What security permission requirement do I need to check on the machine where it does not run?

Hello everyone,
I've officially lost my mind. I'm trying to sign a third party dll which I wont beable to get a PIA from the company for. Based on microsofts documentation I should beable to use the Ildasm.exe tool similiar to this: ildasm assembly.il /dll /key:publicprivatekeyfile.snk but i get an error message back from ildasm stating that "INVALID COMMAND LINE OPTION: /dll". I am staring at the ms documentation telling me to use that option. What am I doing wrong here?
Thanks!

ildasm is the IL Disassembler. It looks like you're in need of ilasm, the IL Assembler.

Hi
I have faced one problem on calling the native dll's functions from C# .Net coding.Actually i wrote
one dll to control the Digital Multimeter in a remote programming mode through GPIB interface.
Initially i have imported the win32 dll provided with GPIB driver in my coding and tried to send the
data to the Digital Multimeter, Whenever i send the data, it throws this Exception
" System.AccessViolationException: Attempted to read or write protected memory. This is often an
indication that other memory is corrupt." , but i will send the data from VC++ application,its
working fine. Is there any specific settings needs to do? Please help me to solve this problem.
For your reference i have pasted the header file function ,VC++ coding as well as C# coding here.
Header file function
----------------------------
extern long int _cdecl ieee488_send (long int,char *,unsigned long,long int *);
#define send(addr,s,status) ieee488_send(addr,(char *) (s),0xFFFF,(long int *) status)
VC++
----------
send(temp,info,&status);
info is character pointer
Status - int
C# -- I have tried in the folowing ways
------------------------------------------------------
1. [DllImport("IIEEE_32M")]
public extern static int send(int address,string strCommand , ref int status);
send(inGpibAddress, Command, ref inStatus);
2. [DllImport("IIEEE_32M")]
public extern static int send(int address,string strCommand , out int status);
send(inGpibAddress, Command, out inStatus);
3. [DllImport("IIEEE_32M")]
public extern static int send(int address,[MarshalAs(UnmanagedType.LPStr)] string
strCommand, out int status);
send(inGpibAddress, Command, out inStatus);
4. [DllImport("IIEEE_32M")]
public extern static int send(int address,[MarshalAs(UnmanagedType.LPStr)] string
strCommand, intptr status);
send(inGpibAddress, Command, out intptr inStatus);
Thanks in Advance
Thanks and Regards

I think the problem is with the string type. Have you tried using a byte[] array?
Also, you may want to write a wrapper function using MC++ and use the pin on the byte[] array to make sure the garbage collector doesn't move that memory since it's being used by a native sub-routine that can't be notified of pointer re-locations. Just a thought

I've never tried using a #define with P/Invoke, but if I were to guess, I'd say that may your problem. I suggest you try having your C# calling the ieee488_send method instead of the define'd send:
public extern static int ieee488_send(int address,[MarshalAs(UnmanagedType.LPStr)]string param2, uint param3, out int status);
|

I'm no C# expert, but if the ieee488_send method is expecting a pointer for the second and last arguments, then I think you need to declare them BOTH using "ref" (as you did the last one).
<br />
[DllImport("IIEEE_32M")]<br />
public extern static int send(int address,ref string strCommand,int xx, ref int status);<br />
send(inGpibAddress, Command, 0, inStatus);<br />
Also, does the method expect 3 or 4 arguments? In your VC++ example you have 4 arguments in the header file definition for ieee488_send. In C# you are only defining it as having 3 arguments...

There go my people. I must find out where they are going so I can lead them.
