Re: Finding the number of Occurance of a string - C# Discussion Boards

Hi i load an image on label control.but with tab control ,control is not selected .
How can i make this control selected with tab control

Hello, I need to do some gui automation work with Java from C#.

I apologize, there are two ways:

1/ throught .net 3.0 System.Windows.Automation,
It seems to be incompatible with Java.

2/ throught Java Access Bridge throught interop with functions in WindowsAccessBridge.dll
However, all called functions /isJavaWindow, getAccessibleContextAt, getAccessibleContextFromHWND, getAccessibleContextWithFocus/ are not working for me.

Does anybody have any examples ?

Hi,
Iam new to c# can anyone help me to find the no of occurance of a string eg("C") in a set of string eg("Couch") without any loops.

thank you,

Regards

Praveen

You could split the string on the substring you're looking for, then see how many items are in your array. A regex would also work.

Christian Graus - Microsoft MVP - C++
Metal Musings - Rex and my new metal blog

Both methods outlined by CG would work, I'd go for the Regex one as it's more powerful and infintely more configurable should your requirements change.

If you need any help with Regexs this[^] site is very good, if that doesn't help then just ask.

Just Google it.
Failing that try phoning Green Alien | [Alien]

Use String.Split to find the number of character count.

for example :

"infintely".Split("i".ToCharArray()); returns an array of count 3.

so number of i in "infintely" is 2.

Ashish

Wasn't that meant to be for the OP?

Just Google it.
Failing that try phoning Green Alien | [Alien]

You can replace the string that you are looking for with an empty string, and check the length of the original string with the resulting string. Divide the difference in length by the number of characters in the string that you are looking for to get the number of occurances.

Hello,

I want to be able to update a connection string that I have in my app.config file. This is so that the customer can change the connection to another server or database.

Can anyone give me any example code. I am using C# 2005.

Many thanks in advance,

Steve

In .NET 2005 there's a new configuration framework that simplifies writing config settings per user or per app. If you add a settings file to your project, you can add settings and then access them directly ( they get written to the file for you ). Check the MSDN for more info. One thing, - I created a new settings file and it didn't work, the file you need is under a folder called 'profile' and you actually access it from Profile.Settings.Default.Propname, where Propname is the setting you created.

Your other option is to open the app.config using an XmlDocument and changing the values using XPath/DOM code.

Hello

I am using my.settings to create a application scope connection string.

The customer would like to change this if they want to connect to another database, and this should update the app.config file with the updated connection string.

My problem I have into the setting and create a connection string (easy). But I don't know and can't find out to update and save the new connection string.

My.Settings.cnnString = "This is example connection" 'Error read-only property

I am using vb.net 2005

Can anyone help,

Thanks in advance,

As I said there's not much point in asking here since we're C# developers and I for one have developed in VB.NET but not recently so don't know about My.Settings, people in the VB.NET forum should know. Roll eyes | :rolleyes:

the file you need is under a folder called 'profile' and you actually access it from Profile.Settings.Default.Propname,

I am sure what this Profile.Settings.Default.Propname is, can someone possibly give me an example.

Many thanks,

I realised there was a folder called Profile with a settings file in it. I hadn't seen it, I'd followed the instructions on the MS site and created a new settings file, which the IDE did, but which then was not mapped to the Profile.Settings stuff. It's all stupid IMO, but I can see now how to make it work. In the meantime, I wrote my own code to serialise a struct with all my settings in it to XML, and to expose those properties via a static class.

Hello,
thats my problem:

Decimal _ContentDistributionResolution = 0;
....
....
_ContentDistributionResolution = myReader.GetDecimal(12);
...
...

In the Database ist the ContentDistributionResolution column from Datatype Decimal (accuracy: 5)...
The System.Converte methode dosent work...

Define 'doesn't work', Have you tried this :

object o = myReader.GetDecimal(12);

in the debugger to see what object is being returned ?

Sorry Roll eyes | :rolleyes:

In C# how to get the line number and file name from which an exception is raised.

In C++ we have the macro __LINE__ to do that. Want to know the substitute in C#. or Is it possible to use the macro __LINE__ in C#. if YES , let me know how is it possible.
