Hi,
I need to display different UI controls based on the row in the same column. for eg.
DataGridCell(row1,col1) should have a combo box,
DataGridCell(row2,col1) should have a Textbox,
DataGridCell(row3,col1) should have a multiline Textbox,
DataGridCell(row4,col1) should have a Date Picker
I can placed the respective controls when ever user select the perticular cell. Now i need the controls to be visible all the time not only on selection.
Can anyone help me out in resolving this problem? I have a customized class which inherits the DataGridTextBoxColumn.
Regards,
Kais

Dear gurus,
I am de/serializing objects with Serializers (e.g. XmlSerializer). It works just fine.
But each time if I add any attribute to my classes which I serialize (let's say I update my class to a new version) , then the appropriate serializer is not able to deserialize my classes. This behaviour is clear to me of course.
But how can I improve this behaviour?
My Idea with deserializing is the following:
1) Extend the class which has to be de/serialized with a version-info-tag
2) Before deserializing, read the version-info first from file
3) Dependent on this version, decide which Version of the class to use for deserialization
4) Read the file (deserialize) now with the right class-version
Can somebody help me with this topic?
Thanks a lot in advance

Hello,
I am using MFC - ActiveX control in C# based windows application.
I am not able to debug the control with the C# application while it is possible with the MFC applcation.
I want to call a function on buttton click event of windows application.
The function is in ActiveX control.
I have given the path of the exe in control also enabled the Unmanaged debugging in Windows application, but when i start debug it doesn't populate the exe, instead it comes out and ready for debug again.
Is it possible to do so if yes then HOW.
Thanks.
Byee..

I want to apply certain commands on the asseblies after they will be placed in the GAC during installation.e-g Tlbexp Assembly1.dll or regasm Assembly1.dll.
Currently i am running the Setup from batch file that starts the setup.Now the Setup will install the assemblies on to the GAC and also copies them into the installation path.
But this is not a good pocedure to accomplish the task.
Is there any good alternative?
Regards

I need to code my application in 3 tier.
But i dont have exact idea what to do.
I know the concept well, but dont understand how should i proceed.
Can anyone help me,

Happy coding

Just googling for it can give you some good links showing the concept. Anyway, try this codeproject article itself. The architecture is all there.

Okay, so I'm very new to C# (and to programming in general for that matter), but I've come across this idea of boxing and unboxing that seems completely odd. In my understanding, it is a shell game of sorts between a referenced type and a value type. It seems to me that this might save in resources, and that it is similar to casting in C, but it is unclear to me. If anyone could give a reason as to why someone would want to use this technique, I would be very grateful.

You can cast anything to the type Object, and back again. This is frequently used when a method takes parameters that can be any data type. For instance the String.Format method:
string s = string.Format("{0}{1}{2}", "The answer is ", 42, ".");
What really happens here is that the method takes an array of objects:
object[] temp = new object[] {(object)"The answer is ", (object)42, (object)"."};<br />
string s = string.Format("{0}{1}{2}", temp);
The strings already are objects, so they can be casted without boxing. For the integer value, though, a new object is created on the heap and the value is copied into the object.

I want to register a .NET assembly as a library, so that any program can import it. As easy as you do with "using System;" how can I do that?
Thank for you help.

You can add the assembly to the GAC[^] (Global Assembly Cache). That way, the clients of the library can all share the same assembly, instead of each one having a copy in its application directory. Have a look at gacutil[^], which is a utility in the SDK that allows you to add/remove assemblies from the GAC.

i used the month calendar from the article "ANOTHER MONTH CALENDAR" by Patrick Bohman.
got some questions regarding the control:
1.
the flow of my project is to select a date, give its corresponding datecode(holiday, special holiday or regular day) then select another date.
everytime i choose a another date after the first one, seems i couldn't get the right date selected. i used the DaySelected method. and gets the clicked date by
string[] m_daysSelected = e.Days;
but seems i couldn't get the right days.
how do i do that?
and by the way, i have to remember all the selected dates plus its other corresponding data before i get to save the entire selection of the year.
is that possible?
2.
i have a combo box consisting of different years.
each year has different formatted dates.
how do i copy the formatted dates of the entire year that chosen from the combo box to the recent year?
thanks a lot.

Then why don't you ask your question in the comments section of the article itself? That would be the right place.

1. Spell it correctly: IEnumerator
2. Type this into the top left textbox on CP.
3. Hit enter.
4. Look at the search result list[^].
5. Determine that this article[^] is probably rather good as a starting point.

If Robert's response wasn't what you were looking for...
1. Drop the "I" and try the contruct: Enumerator
2. Type this into the top left textbox on CP.
3. Hit enter.
4. Look at the search result.
If neither response helps, try asking a conherent question next time.

i'm using sockets, i want to disconnect this socket after connection. but i can't disconnect it. it throws "An invalid argument was supplied"
i write "sck.Shutdown(SocketShutdown.Both)", but it can't work
what must i do plz help!!!
|

If you receive a SocketException when calling Socket.Shutdown(), use SocketException.ErrorCode to obtain the specific error code. Once you have this code, refer to WinSock 2 error code documentation[^]for a detailed description of the error.

Hi,
-Is it posible to recieve information about the stacktrace/execution history at runtime??
thx.
|
|
|
|
|
I believe that the easiest way is to just throw an exception and catch it.
string trace = null;<br />
try { throw new Exception(); } catch (Exception ex) { trace = ex.StackTrace; }

StackTrace st = new StackTrace();

Totally off subject, I got a copy of xacc.ide the other day, and it exceptions on load. No meaningful information, just ungracefully croaks.
