i am getting error in this foreach loop...
ButtonList contains List of Buttons and LinkButtons.
foreach (Button str in ButtonList)
{
}
|
|
|
|

I just took a sleeping pill and can't think clearly, but this could work.
foreach(Control ctrl in ButtonList)
{
if(ctrl is Button)
{
Button myButton = (Button)ctrl;
//Do work
}
else if(ctrl is LinkButton)
{
LinkButton myLinkButton = (LinkButton)ctrl;
//Do work
}
}
Ask others first since I am way over due for sleep, and good night. That 'should' work though.

LinkButton, Button and ImageButton dont have a shared base class, but they do have an interface which they all implement called IButtonControl. So this will work for you (asuming that IButtonControl has the property/method you are trying to use)
foreach(IButtonControl btn in ButtonList
{
...
}

As others said, you have to write your own code. As a pointer, a picturebox is not a magic image processing library. It's a tool for people who are too inexperienced to know how to paint an image onto a form ( although that's not too hard ). You'll have to write code for all of this, and the picture box will just get in the way.

Hmm, quick search on Google resulted in this as a result, the first one to be exact.

And it is right here on CP! Even better, the conclusion says the exact words 'reading and writing', worth a look at.

h5,h6,h7 and h8
here b and h stands for row and nos stand for columns
i am not familiar with windows data grid so it would be great if someone suggests me a way thru some sample code.
Thank you

Oh! nos = numbers
How about you reask the question, in better english, and no text speak?

Hi,
to better understand the problem,
I have a windows data grid with some data filled up.
now i want to edit only some cells (B5,B6,B7,B8) of 1st,3rd,5th row only in that datagrid,
B5- 5th cell of Row
B6- 6th cell of Row
.
.
.
i need sample code for this.
Hope this is clear now.
Thanks

Hi people!!!
I had to develop an application that has to work as standalone and also as "add on" of some ERP systems. One of the things done in my program is to have an object serialized to an XML File.
It works 90% of the time... but under ONE of the ERP Systems (SAP) I get a System.InvalidOperationException: "There was an error generating the XML document", InnerException is "Could not load file or assembly 'Swissdec..."
What is driven me crazy is that this exception is generated inside that assembly...
Does somebody have an idea???
here is the stack:

Happy new year to everybody!
I did some researches and what I understand is that my app does not generates correctly the "MyProject.XmlSerializers.dll" ... Or else it uses another xmlserializer instead of this one.
As said above my app is an Addon and is called from an outside application. This may confuse .NET and I found out that using the GAC may resolve the problem.... But I don't wanna do that. Any other suggestion would be appreciate!!!

Hi,
When i try to connect a client with a listening server, no connection is established. In the client, i get the LocatEndPoint as 0.0.0.0 : "port number".
It is ok in some particular system.
Here is the code for server listening :-
strHostName = Dns.GetHostName();
IPHostEntry ipEntry = Dns.GetHostByName( strHostName );
aryLocalAddr = ipEntry.AddressList;
Socket listener = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
listener.Bind( new IPEndPoint( aryLocalAddr[0], 399 ) );
IPAddress.Loopback, 399 ) );
listener.Blocking = true;
listener.Listen(-1);
listener.BeginAccept( new AsyncCallback( app.OnConnectRequest ), listener );
Code for client :-
m_sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint epServer = new IPEndPoint(IPAddress.Parse(IPaddress), 399);
m_sock.Blocking = true;
onconnect = new AsyncCallback(OnConnect);
m_sock.BeginConnect(epServer, onconnect, m_sock);
Regards,
Yesuprakash

I'm not new to C#, nor to programming in general, however, I can't seem to find any information on this anywhere.
I need to know if there is any way to replace a reference to a managed library used by another library, to which I do not have the source.
Because that probably wasn't very clear, here's an example of what I mean.
I have a library, A.dll, that references another library, B.dll. However, the version of B.dll that is referenced is dated, and I want to replace it with a newer, more secure B.dll. I already know that its implementation will be supported, because nothing has changed in terms of how it is used. I cannot simply disassemble and reassemble the library, because one of the source files is unusable when I do so (I do not know why, to be honest. It just generates random symbols.)
Is there any way to do this?
|
|

|

Nevermind. It seems that I've been able to remedy the problem by disassembling it into MSIL, editing the assembly language to reflect the new library, and reassemble it. Problem fixed.
