Can anyone help me?

Hi, quick question.
Anyone know how to use quotes in c#.
In vb.net, I can write:
Console.Writeline ("This is a " & chr(34) & "quote" & chr(34));
which would output:
This is a "quote"
So how can I do it in C#?
PS: I need a quote ("), not a hypen thingy (')

You can insert meta-symbols directly into text after "\" symbol.
Your sample:
Console.WriteLine("This is a \"quote\"");

Hi Andy
Another possibility that I like is putting a "@" in front of the string.
THen you can show the "'s using double ""'s
For example:
string quote = @"Andy said ""hi!""";
this also lets you write backslashes without needing the ekstra backslash.
For example:
string path1 = "C:\\data\\text.dat";
string path2 = @"C:\data\text.dat";
now you have choices 
- Jakob
Three kinds of people in the world:
- Those who can count..
- Those who can't!
|
|
|
|
|
another choice is this:
char quote = '"';
string str = "This line have " + qoute + " quote. " + quote;
result : This line have " quote. "
|
|
|
|
|
That code might prove quite inefficient, though. You risk that the compiler will box the char values, and the actual code produced will be:
char quote = '"';<br />
object[] tempArray = new object[] { (object)"This line have ", (object)quote, (object)" quote. ", (object)quote };<br />
string str = string.Concat(tempArray);

b { font-weight: normal; }

Hi,
I'm trying to import a tlb file, but always get the following error:
---------------------------
Microsoft Visual Studio
---------------------------
A reference to 'C:\Win32App\ingr\IDISP\bin\idisp.tlb' could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component.
---------------------------
OK
---------------------------
Yet, my colleague can import the same tlb correctly. I've tried it on another pc and it worked idd.
Crazy thing is, it didn't work some time ago, but in meantime I've re-installed my system, yet no difference.
What could be the problem? I'm still in training for our product, but this file is key in development soon...
TNX!
Coulda, woulda, shoulda doesn't matter if you don't.

Hi.
In a simple applicatin(Phone Book), I have 2 tables in my DB(SQLServer or Access).
A table for id,name,family and another for personID and tel.
now when I want to add a person, I must add record to both tables (name and phone),
but I don't know how can do it with C#??!! (with one command add to two tables???)
I'm beginner in DB !!
Best wishes

If you are using SQL Server then you can use a Stored Procedure[^] to populate both tables at once. You can also separate SQL commands with a semi-colon so that you can put two SQL commands into one SqlCommand object.

Hi,
can anyone help? I have some question on how the webCam works and how to retrieve images from it. I try to get the image and display it on the Web.
Questions :
1. Where does webCam stores the images captured? Or Do I need to specify a Folder for the WebCam to deposit the images captured?
2. How to use C# code to retrive images? where to retrieve the images?
3. Are all images captured by webcam will be in order according to time?
Please help.
Thank in advance.

I have the same dilema, but, if you don't mind using COM objects, there's a very good ActiveX that I use in VB and it works for me in C# also. It's a free object. It's call exVidCap.ocx. Look for it on the web. http://www.shrinkwrapvb.com/ezvidcap.htm[^]

Hello Experts,
I want to read .cer file generated by RootCA. I want to encrypt scramble it with some garbage data and make .cer file unsuable, then I want to remove the garbage data from .cer file so it could be useful again.
I wanna do it because if I give anybody a .cer file to install it on some machine, he should not be able to steal it. The only way this .cer file could be installed in Authority Store is by my program which gets the confirmation before removing the garbage data from a webservice and sends that webservice client's IP and username.
I tried opening the file in C and C++ both couldnt read the file. Can I do it in C#. If I can then how?
Thanks Alot in Advance

Hi,
I need to write an error reporting tool. Part of its logging mechanism is querying all installed software and hardware from the system. Can anyone point me to a way to query information about the software packages installed on a computer in C#?
Code project features a nice article explaining how to query the hardware (http://www.codeproject.com/csharp/hardware_properties_c_.asp)
But I would need to query installed software packages too. Any help is appreciated.
Thanks in advance
Ingo

You could look into the registry under the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall.
Basically everything listed under control panel/Software is listed there (including name, manufacturer, version...).
You can access the registry via the Registry class in the Microsoft.Win32 namespace.

Thank you for the hint.
