Here[^] is my take on the "Nullable Comparison" issue. I can't explain why it does what it does, I can only observe and live with it.
 Luc Pattyn [Forum Guidelines] [Why QA sucks] [My Articles]
I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that. All Toronto weekends should be extremely wet until we get it automated in regular forums, not just QA.

Use OnMouseDown, OnMouseUp and OnMouseMove events. Handle property Form.Location based on mouse move

Do you know how to use TCP/IP Or UDP?

It is easy as long it is same process. But in your case it is more than just sending listbox data.

If you want to print use either CrystalReports or DocumentPrinter. If you chose DocumentPrinter(I hope it is correct name) you would need to use GDI+ to print to Document. I Suggest to use CrystalReports, because it is easy.

but i will i add label, list box,textbox etc in crystal report.is this possible to design form in crystal report?
|
|

No. CrystalReport is only for showing and printing. It isn't design to use Textbox or any control that has user input. In design view, you only see on how this invoice or other type of report would look.

You want to actually print a Screen shot of that form?

Hi,
I have upgraded remedy system to 7.1 and I have developed a .Net C# application which retrieves the data from the remedy database pertaining to my company. I am able to retrieve the data for a query which retrives a single record only. For queries supposed to be returning multiple rows, data is not fetched and an ODBC exception is thrown with native code 9055. I searched and found a ARS error document . Below the description of error code 9055 in the document.
*******************
9055
Error
The VUI import file is in an incorrect format.
No VUI definition from the file was retrieved during the import operation. The format of the
import file was corrupted so that it contains no VUI information.
*******************
No idea what does this mean.
Additional information regarding the exception.
Native error: 9055
Message: [AR System ODBC Driver]Data types are not appropriate for relational operation
Source: ARODBC70.DLL
SQL State: S000
BMC error reference document provides some explanation to the above message
313
Error
Data types are not appropriate for relational operation.
The data types of the fields used in a relational operation are not consistent with the operations
allowed for that operation. See the Form and Application Objects guide for information about the
allowed data types of operations.
If we have a problem with the datatyes, how we are able to fetch a single record and not the multiple records.
All was working with Remedy 6.0 and there were some changes with the database and I started to get these errors. How can I overcome this and fetch the data.
I am able to open the connection successfully.
KINDLY TREAT IT AS URGENT and any guidance to this is highly appreciated.

I've looked and haven't found anything about this anywhere, so before I write an article about my solution, I thought I'd ask here.
The FileSystemWatcher supports one or more NotifyFilters when watching for changes to a folder/file. However, if you have more than one NotifyFilter specified, there is apparently no way (at least with a single FileSystemWatcher) to determine *exactly* what change occurred that caused the Changed event to be posted.
Am I correct, or am I just not seeing it?.45 ACP - because shooting twice is just silly

Apologies for lack of formatting, doing this from my phone.
The NotifyFilters enum is decorated with the [flags] attributed. This means the enum can be treated as a bitwise flag. You can and and or such enumerations.
It's serendipidous that I can answer this, I had an interview where the asked about such enumerations. I tanked on that part, but wouldn't now!Antoine de Saint-Exupery: Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

It's not about the enums, it's about determining exactly what change took place to trigger the Changed event..45 ACP - because shooting twice is just silly

| No, there's no standard way to see what exactly has been changed in the file (for example). Die Energie der Welt ist konstant. Die Entropie der Welt strebt einem Maximum zu.

Actually that's a good thing, because I haven't been able to find a way without excessive coding..45 ACP - because shooting twice is just silly

I just found this on MSDN.
private static void OnChanged(object source, FileSystemEventArgs e)<br />
{<br />
Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType);<br />
}
Does the e.ChangeType give any useful information to determine exactly what change occured?Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.
Honestly. It's the honest ones you want to watch out for...

Nope. It returns what I refer to as the "bulk" Changed event (or Renamed, Created, Deleted, etc)..45 ACP - because shooting twice is just silly

Sentence like this
_toolTip.SetToolTip(toolStripBtnAbout, "About window");
caused error "cannot convert argument 1 from ToolStripButton to Control"
