Hi all,
How can I create a short cut key any button in .net. Suppose I have a button named btClick and button text as "Click". In this I want to keep "C" as short cut key for this button click event. Can I do it in Windows and Web applications too?. If so please tell me how in both type of applications?. Thank you.

Please don't cross post. Choose a forum, and ask there.
I answered this in another forum, and I've also asked you not to cross post, before.

You cross posted to the ASP.NET forum, both with this question, and the one above. Why ?

Dear Christian,
I am not getting reply for these queries. Please tell me if you know this please. Even tell me if know it for Windows only. Give me some code snippet or links if possible please.
can any body tell me the code for customizing the crystal reports as per the given format in either windows form or in web application.
Letus suppose my client has few papers in already printed format. "Company Name : " in that empty place "Akebono Soft" must be printed. In this way the crystal report should print the content in specified way only.
First of all can I do it. If so, how can I do it. Thank you.

I'm planning to extend a large .NET project (3 solutions / 20 projects) to Unix through Mono (there should be separate autorun installers for Windows, Linux and Mac OS on a CD for end user).
There are many problems. The big one is the use of platform-specific features (registry, API calls) and the other that it is all made with VS 2003 IDE.
I know there is not any universal answer for this, but any help or links to information resources would be appreciated - thanks a lot.

Hi all
I have an app that hosts the IE AxWebBrowser control. I would like to have the app automatically resize for each loaded page to the smallest width (within reason) that can display the page without a horizontal scoll bar appearing. It would be great if this was a simple calculation but in the worst case it is also acceptable for me for that value to be determined theough multiple tests (i.e. best would be some magic "int RequiredWidth()" method, but acceptable would be a "bool HasHorizontalScrollbar()" method that I can use to converge on the optimal width.
Does anyone know how I can implement either of these two?
Thanks!

Hi,
I am considering various obfuscators and protection systems and am considering .Net Reactor in view of it's performance and price.
If anyone has any recommendations/comments, I would appreciate the feedback.
Thanks.

is there any possibility in the 2.0 Framework to have a preview of a webcam and to record the stream to disk

You need to download and install the Platform SDK, which includes the DirectShow library. It has samples of this sort of stuff ( in fact, tehre are also samples on the site itself )

Hi,
first of all, plz excuse my rusty english 
I'm writing a little wrapper in c++ .net which allows me to access some old unmanaged win32 c++ dlls from a c# program.
There is one function in the dll which drives my crazy.
It wants an array of struct as an argument, called by reference.
Its code is looking like that (a bit simplified):
the struct in c++.net and in the dll code:
<br />
struct ParaList<br />
{<br />
BYTE adress;<br />
WORD length;<br />
};<br />
the dll function prototype (in the dll -> non c++.net):
<br />
BOOL RequestValues(ParaList list[], int listlength);<br />
I included it into my c++ .net like following code:
<br />
[DllImport("mydll.dll",EntryPoint="_RequestValues@12")]<br />
extern "C" bool_cdecl RequestValues(ParaList *list, int listlength); <br />
What it does is: I can request the values of some parameters by executing the RequestValues() function.
After that I can read the requested values by executing a readfunction().
I'm calling the function in managed c++.net like that:
<br />
ParaList list[8];<br />
list[0].adress = 0x1;<br />
list[0].length = 0x1;<br />
bool error = RequestValues(list, 1);
The problem now is: when the list only has one parameter (like in the example above) the function works correct. But when I request more than one parameter, the dll will put out some error.
In a c++ mfc example the dll is working correct!
I think the problem is related in the memory management of c++.net.
I'm pretty new to c++.net. Am I right that in managed c++.net the allocated memory for an array must not be in sequence? So the single elements of the array are distributed all over the memory?
In that case the dll would get only the pointer on the first array element but the second element is not the neighbour, so the dll reads garbage when it wants to read the data of the second array element.
I tried a few things with __pin and __nogc keywords which led to nothing 
Does anyone have a clue how I can tell c++.net to allocate the memory for the array in a coherent memory area?
Thanks for reading this!

It's easier to use pinvoke to call functions from c++ dlls.
There is a C++/CLI forum, if you ask there, Nish is bound to find it and help you.

Hi,
thank you for your reply!
Finally I found the problem by my own.
The problem was the structure:
<br />
struct TMP<br />
{<br />
DWORD x;<br />
WORD z;<br />
};<br />
A sizeof(TMP) told me that it's 8 Bytes big.
The strange thing here is that a DWORD is 4 Bytes and a WORD is 2 Bytes big (confirmed by sizeof(DWORD) and sizeof(WORD). If you count it together it's 6 and not 8???
The DLL function expected an array of 6 Bytes structs.
What it got was an array of 8 Bytes structs, which led to that the Dll got garbage while it was reading the second array element.
What I did now, was splitting up the DWORD into two WORD variables:
<br />
struct TMP2<br />
{<br />
WORD x1;<br />
WORD x2;<br />
WORD z;<br />
};<br />
sizeof(TMP2) says that it's 6 Bytes big now. Really strange.

There is nothing really strange about that, C (and C++ I guess) pads all its structs
so all elements are "naturally aligned" (to an adr that is a multiple of their size),
and aligns the entire struct to the size of the largest element, in your case 4B due to the DWORD/int.
The reason is the compiler can then emit code that manipulates 4B quantities without worrying
about alignment and/or achieving highest performance. (Some processors do not know how to
load a DWORD from an unaligned adr, others do but take more time to do it).
The net result is:
1)
if your struct's size is not a multiple of 4 but contains elements sized 4B, the struct will
act as if its size is a multiple of 4B (even when sizeof shows otherwise).
2)
if the elements in your struct are not "naturally aligned", the struct will be padded with
extra bytes to achieve the natural alignment (=each element gets aligned according to its size).
So
struct {
byte a; // offset 0
short b; // 1 ? not naturally aligned
byte c; // 3 ? OK
byte d; // 4 ? OK
long e; // 5 ? not naturally aligned
}
gets compiled as if it were:
struct {
byte a; // offset 0
byte bDummy;
short b; // offset 2
byte c; // offset 4
byte d; // offset 5
byte eDummy1;
byte eDummy2;
long e; // offset 8
}
The function you used was an old one, relying on a stride of 6B, so something special needed
to be done. In C (and C++ I guess) there are compiler switches and/or pragmas to disable
the alignment/padding. In C# your splitting the 4B into two 2B elements is probably the
best way to get what you needed.

Hi ~
For the databinding for the control class
i.e. Control.DataBindings.Add(string propertyName,object dataSource,string dataMember)
for the parameter of dataSource and dataMember, how can i bind the value of the control to the specific in array
e.g. if i have a class
public class Person{
public object[] extras
}
then i want to bind the control with the second element in Person.extras i.e. Person.extras[1]
i try the following ways, but not success
controlObj.DataBindings.Add("Text, person.extras, new object[] {1});
and
controlObj.DataBindings.Add("Text", person, "extras[1]");
Thank
|

The Control i need to being binding to is allow to bind the single value only, such as TextBox, can just bind to a sigle value. But ListBox can bind to a list or array because it allow multiple to display in the control

Thx in advance

I heard a collegue of mine mention this, but uncertain of its truth...
software built with Microsoft's .Net (and later) compilers <br />
creates executables in a "common format" that can be run through<br />
commercially-available disassemblers to fully recover the original<br />
source code. the protection against this is to use scramblers.
Can anyone veryify this?
Thanks,
Johnny

Simplistically, code written against .NET is compiled into IL (intermediate language). This IL can be reversed back into source code. Obfuscators can be used to make this reversing much more complicated.
Now, it is important to note that no source code (in any language) is 100% safe from reverse-engineering. Given the time/motivation you can reverse any source.

Follow up question: is it (now) easier to reverse engineer code compiled in .NET?

From unprotected code, yes.
