Hi,
I have SMS gateway and they only allow SMPP protocol to be used to send SMSs.
Is it possible to send use SMPP using just C# .NET Framework or I should use a third party?
if not possible, any free third-party?
Thanks,
Jassim

So what is your problem here.
Step 1:
Place a link or button on top of List.
When user click open a popup window load column name from sql to gridview wich check box column.
here is query to load all column name from a table.
SELECT Column_name
FROM information_schema.columns
WHERE table_name = 'YourTable_Name'
ORDER BY ordinal_position
From popwindow get all the selected column name and display the selected column in your main form.
Step 2:
By default load all columns and make visible selected columns .
Place a link or button on top of List.
When user click open a popup window load column name from sql to gridview wich check box column.
here is query to load all column name from a table.
<pre lang="SQL">
SELECT Column_name
FROM information_schema.columns
WHERE table_name = 'YourTable_Name'
ORDER BY ordinal_position
</pre>
From popwindow get all the selected column name and make visible tru and false for the selected columns.

Hey,
i was working on some API for networking when i implemented some sort of logging and Reporting, in certain situations when all of the sudden my Test project in WPF didn't worked as expected. After some debugging i found a Cross-Thread exception that was caused by some bindings. The API is using some High Level of threading and Tasking support.
The problem was that i was attached to a Event that was trigger in a Non-Dispatcher Thread, and inside my ViewModel i did not synchronized the code. The Whole application was still running ( AppDomain had some global exception Handling ) but the point is, this external exception ( as seen from the API side ) had noting to do with the API but prevented it from working by throwing an Exception and stops the execution of the code after the Event Trigger.
I learned due my time as a Developer that some sort of "General" exception catching should be prevented where possible. This does not mean an empty TryCatch block ( What is actually even very Bad ).
So my Question is:
Should i break this Design guide and more, should i catch Exceptions in general when i Invoke an event? The event handler could Throw some exceptions what i do not expect and i should not worry about. And last but not least: If jes, what to do when we catch an event?

Nah. If you did and an exception occurs, how would I even know?

My problem is about how to call a c# function like this
string Block = "1111111111";
string a = "87654321";
string m = "2222";
string c = "11";
string u = "99";
string v = "00";
byte[] result = W(
SoapHexBinary.Parse(a).Value,
SoapHexBinary.Parse(m).Value,
SoapHexBinary.Parse(v).Value[0],
SoapHexBinary.Parse(u).Value[0],
SoapHexBinary.Parse(c).Value[0],
SoapHexBinary.Parse(Block).Value
);
from VB.NET
Dim Block As String = "AAAAAAAAAA"
Dim a As String = "99999999"
Dim m As String = "3333"
Dim a As String = "77"
Dim u As String = "07"
Dim v As String = "00"
Dim result As String = ""
result = W(a, m, v, u, a, Block)
a, m and Block are not accepted.
I'm not a C# expert so I guess that there is something to be done in order to correctly address strings and arrays between the two languages. Must be kind of basic rule I ignore...
Anybody can help?
Thanks in advance.

You're not calling it the same way as the C# code. Without knowing anything about what W is, the equivalent code would be:
Dim Block As String = "AAAAAAAAAA"
Dim a As String = "99999999"
Dim m As String = "3333"
Dim a As String = "77"
Dim u As String = "07"
Dim v As String = "00"
Dim result As byte() = W(
SoapHexBinary.Parse(a).Value,
SoapHexBinary.Parse(m).Value,
SoapHexBinary.Parse(v).Value(0),
SoapHexBinary.Parse(u).Value(0),
SoapHexBinary.Parse(c).Value(0),
SoapHexBinary.Parse(Block).Value
)

Thanks Dave,
W is like below
Public Shared Function W(a() As Byte, m() A s Byte, v As Byte, u As Byte, u As Byte, block() As Byte) As Byte()
It seems to been accepted now exectp getting an error on the
SoapHexBinary.Parse(c).Value[0] param
where 'an identificator is needed for 0'
|
|
|
|
|
Whoops. I forgot to change the square brackets to parenthesis.
|
|
|
|
|
so it's SoapHexBinary.Parse(c).Value(0)
 right, you got it, this seems solved.
But now VB.NET is arguing  about
a, m and Block...
Dim result As Byte() = W(SoapHexBinary.Parse(a), SoapHexBinary.Parse(m), SoapHexBinary.Parse(v).Value(0), SoapHexBinary.Parse(u).Value(0), SoapHexBinary.Parse(n).Value(0), SoapHexBinary.Parse(Block))
(translated)
Can't convert the type value 'System.Runtime.Remoting.Metadata.W3cXsd2001.SoapHexBinary' into a 1 byte dimension matrix.
Hope you can help again.
Thks

Solved.... had it under the eyes for the whole time...
a, m and Block misse the .Value property!
Dim result As Byte() = W(SoapHexBinary.Parse(a).value, SoapHexBinary.Parse(m).value, SoapHexBinary.Parse(v).Value(0), SoapHexBinary.Parse(u).Value(0), SoapHexBinary.Parse(n).Value(0), SoapHexBinary.Parse(Block).value)

When i chose a file to up load it says

That's a code dump: and it's both rude and unhelpful.
It's rude because it says "I'm too lazy to work out what info you need: my time is far more important than yours"
It's unhelpful because it doesn't tell us anything about where the error is: we need to know which line is finding the error before we get any idea as to what might be causing it.
So edit your question, remove everything except the relevant code fragment, and tell us which line the error is on.
Help us to help you! Would you want to wade through a pile of uncommented code trying to work out where a problem could possibly be?

Better!
Now - which line is throwing the exception?
There are still lots of potential candidates, and we can't run your code - so we only get exactly what you tell us to work from.
The original error that you got the message from will specify the file and line number in the file.

its this line
Int32 index = container.VisibleIndex;
vs breaks at this point
|
|
|
|
|
So container is null.
This could be either:
((Control)sender).NamingContainer is null
or
it is not a GridViewDetailRowTemplateContainer so the as is returning null
Either way, use the debugger to check which of these is the case.
A positive attitude may not solve every problem, but it will annoy enough people to be worth the effort.

Not much, but probably that tells us what the problem is - or what you should be looking at.
If the error occurs in this line:
Int32 index = container.VisibleIndex;
The the error (as Matt says) is that container is null.
And from the previous line:
GridViewDetailRowTemplateContainer container = ((Control)sender).NamingContainer as GridViewDetailRowTemplateContainer;
combined with the method signature:
protected void DocumentUpload_OnFileUploadComplete(object sender, FileUploadCompleteEventArgs e) The problem is probably that the sender is a FileUpload Control (or it wouldn't have an OnFileUploadComplete) and that it isn;t contained within GridviewDetailRowTemplateContainer - it's more likely to be in a grid view cell or similar.
So, put a breakpoint on the line:
GridViewDetailRowTemplateContainer container = ((Control)sender).NamingContainer as GridViewDetailRowTemplateContainer;
And look at exactly what sender is, and what it's NamingContainer is.
(It might help if you break it out first and examine each part in turn.)
Control c = (Control)sender);
Object o = c.NamingContainer;
GridViewDetailRowTemplateContainer container = o as GridViewDetailRowTemplateContainer;

this is the sender
sender {DevExpress.Web.ASPxUploadControl.ASPxUploadControl} object {DevExpress.Web.ASPxUploadControl.ASPxUploadControl}
|
|
|
|
|
Yes, but it's the container that is getting null - the sender can't be null as it's the class instance that raised the event.
Use the debugger!
