Thanks for the reply ... I know I'm the one asking for help here, but I saw this technique all over the internet, including msdn, only with the MSDN example it is done by calling a function in the catch.
Am I overlooking something possibly or misunderstanding?

There is quite a bit more in that example code, than what you have implemented in yours. The issue I was thinking about is the different exception types... you are using Pokemon exception handling (catch 'em all) - but the example catches each exception type and handles it differently.
However, your exception (no handle exists with that name) is telling us the problem, and it's what Dave said it was - it doesn't exist, and you aren't trying to create it, you're trying to "get" it.

Just because you see a technique all over the Internet does not mean that it applies to your situation.
From what I've seen in your code, it suggests you're trrying to make a single instance app. The code you have is not suited for that purpose at all. To make a single instance app, an application first tries to create a Mutex. If it's successfull, it's the first app instance running. If the creation of the Mutex fails, then you know your app is not the only instance running.
Follow the logic in your code snippet and you will see that it does not follow the logic I just laid out.

I believe I understand now and yes I was trying to make a single instance app.
I had thought a mutex was created as a default and I was trying to find that. Now I have the code set up to create a mutex and if it cannot create it, to bring the minimized app to the foreground.
Thanks for the help.

i have created a login page by c# in visual studio.
if i want to take it as my system login page,what are the next steps to be done?
With out this login authentication no one could access the system.
|
|
|
|
|
Set your Login Page as the startup form and display that Modal dialog. When the authentication succeeds, continue with the application.

i want my login page right after booting.. with out this login no one couls access any features of windows.

You're not going to do that in a C# application.
Your application cannot stop people from using Windows. They have to enter their own credentials to get into Windows to evern see your app, correct? Your app is pointless since you cannot stop a user from terminating your app quite easily.
Now, if you wanted to provide a custom authentication package for Windows to use, you would have to write a Credential Provider[^] and register that with the system. The users can then enter their alternate credentials for your authentication scheme. Oh, you'll be writing this in C/C++, not C#.

No, you can't. Not unless you rewrite Windows...

hi all,
below is my aspx code
<pre lang="HTML"><MKB:TimeSelector ID="TimeFrom" runat="server" DisplaySeconds="False">
</MKB:TimeSelector></pre>
and a text box which is having a date.
<pre lang="HTML">VehicleBookingDate.Text</pre>
I want to save date and time in my database. for that if I want to do like below
<pre lang="HTML"> string t1 = tsTimeFrom.Hour.ToString() + ":" + tsTimeFrom.Minute.ToString() + " " + tsTimeFrom.AmPm.ToString();
DateTime Time_From = Convert.ToDateTime(t1);</pre>
It saves time with current date, where as I want to save this time with this date which is in VehicleBookingDate.Text.
how can I do that.
Thanks
|
|
|
|

Now I get this
<pre lang="c#">
string t1 = Vehicle_Booking_Date.ToShortDateString() +" "+ tsTimeFrom.Hour.ToString() + ":" + tsTimeFrom.Minute.ToString() + " " + tsTimeFrom.AmPm.ToString();</pre>
that is a string but I want to save it as a datetime with the same date which Vehicle_Booking_Date variable is having

Don't use a TextBox, use a Calendar control[^]. You can then create a DateTime object from the two elements.
Use the best guess

I have Windows 7 64-bit and Excel 2010 32bit
I have the following question: I created an user defined functions for Excel in .NET according to the code http://blogs.msdn.com/b/eric_carter/archive/2004/12/01/writing-user-defined-functions-for-excel-in-net.aspx[^]
I'm using now MultiplyNTimes in my Excel 2010 spreadsheet.
if in the cell A1 i type =MultiplyNTimes(2,3,4) i get the correct results (162)
if in the cell A1 i type =MultiplyNTimes(B2,3,4) and I type 2 in cell B2, then I get #VALUE!
Basically my UDF can't accept a link to a cell as argument... can this bug be connected with 64 bit of Windows?
(note thae using the same OS with in 2007 works fine!)
not sure I'm clear.
Have you any suggestion to fix this bug?
Thanks for your time

Nope. It works fine on Office 2007 (32-bit) running on Windows 7 64-bit.
Typically, bitness problems involving Office interop are because of a mismatch with Office, not with Windows. For example, trying to run 32-bit extension in 64-bit Office.
The only time I could get a "#VALUE" error to show up was when I didn't supply 3 arguments.
I used the article you linked to and copied the code exactly (except for changing the GUID) as well as the exact steps for registering the Add-In in Excel.

Yes I tested the same Excel 2007 32bit with Windows 7 64bit is fine..
I have the problem with Excel 2010 32bit with Windows 7 64bit. I thought It was a problem of bit because if I type argument in a cell the UDF does't work (I thought It was a bit conversion problem). While if I directly write arg in function it works.
I also create a function with no args and it works (Excel 2010). So the problem is linked to reading arg from other cells. Very strange

I don't have Office 2010, so I can't test against that.

Hi All,
I have started using Visual Studio 2012 with C# as basic settings. But when I opened a project using Visual Studio 2012, I am not finding Solution Explorer in the ToolBar list on the top of the IDE, generally in Visual Studio 2010 I used to click on that Icon on the top of the IDE just below the File, Edit etc menu.
Can someone please help me in adding that to the list so that my development would become easy intead of going to View menu and selecting the Solution Explorer every time. I have checked to customize that ToolBar on the top, but I dont know which ToolBar item would add the Solution Explorer to ToolBar actually.
Thanks for the help in advance.
Thanks & Regards,
