Khoramdin27-Mar-07 5:25 Khoramdin 27-Mar-07 5:25  Hello everyone, I have a ListView that I wish to run a data search quary on it. I am able to get the raw's information once they are clicked but I was wondering if I can run a query to get the last registered item in the list without clicking on it? as always, thank you very much for your help and have a great day. Khoramdin Re: How to get the data in the ListView? Saikek27-Mar-07 7:01 Saikek 27-Mar-07 7:01  Can you tell more exactly what do you need? And make a sample where it will be used. Because it is not clearly understood what do you want. What is the last registered item ? One nation - underground Re: How to get the data in the ListView? Khoramdin27-Mar-07 7:07 Khoramdin 27-Mar-07 7:07  Hello Saikek, Thank you for the reply. Your message came few seconds before I lose hope! I have a ListView which I am registering and displaying some data once a particular button is clicked. Unfortunatly, the data that is going to be displayed in the ListView can be repeative and I am not intrested to register and display the same data once it has been displayed. That is why I thought if I can run a query to see what has been registed then I can exclude the data that has already been registered and is displayed in the ListView. Thank you very much for your help and have a great day. Khoramdin Re: How to get the data in the ListView? Saikek27-Mar-07 8:41 Saikek 27-Mar-07 8:41  You can try the option ListView.FindItemWithText - that finds item with text, or more interestin (like lingvo style) create textbox, listbox and make event on textbox text changing: private void searchBox_TextChanged(object sender, EventArgs e) { ListViewItem foundItem = textListView.FindItemWithText(searchBox.Text, false, 0, true); if (foundItem != null) { textListView.TopItem = foundItem; } } One nation - underground C# member vars LCI27-Mar-07 5:18 LCI 27-Mar-07 5:18  Does C# have the concept of member variables? I notice that there is no .h file also. Where would they get defined? Re: C# member vars Not Active27-Mar-07 5:26 Not Active 27-Mar-07 5:26  You mean like this class MyClass<br /> {<br /> private string MyMember;<br /> } only two letters away from being an asset Re: C# member vars LCI27-Mar-07 5:32 LCI 27-Mar-07 5:32  In C++ in a .h file, i can delclare a variable say 'm_myvar'. Then i can use m_myvar, globally within the class i.e. (.cpp file). How does it work in C#. I take it that there are no .h files. Re: C# member vars Christian Graus27-Mar-07 5:30 Christian Graus 27-Mar-07 5:30  .h and .cpp files are an artefact of how the C++ compilers worked. There's no reason it's required, I think C# is far nicer in this way.

The class is defined like public class Service1 : System.Web.Services.WebService { public Service1 { } public Myfunc { } } where i am assuming Service one method is the constructor and the Myfunc methid is just a public method in the class. So if i were to declare a member var for all my methods in class to have access to, i would create it inside the class but outside the other methods?? Re: C# member vars Christian Graus27-Mar-07 5:40 Christian Graus 27-Mar-07 5:40  LCI wrote: i would create it inside the class but outside the other methods?? Correct. And, C++ does this: public: int i; int x; C# does this: public int i; public int x; if you don't provide a modifier, it will assume private.

THANKS !!!!!!!!!!!!!!!!!!!!!!!!! One nation - underground Reading Binary files elwoofy27-Mar-07 5:03 elwoofy 27-Mar-07 5:03  I have a question regarding the BinaryReader class and C#. I have been assigned a task at work to read raw data from an application file and search the file for a specific hex data occurance... The problem is when I run the test application I wrote to open and read data from the file the app only prints out one line to the command prompt and its garbage. My question is what is the basic layout to open a file and read raw data? forgive me I'm new to C# and I'm still learning. When reading raw data is there specific formatting I have to take into account? BinaryReader br = new BinaryReader(File.OpenRead(filename)); Byte fileB = br.ReadByte(); System.Console.Writeline(fileB); Binary Data Ennis Ray Lynch, Jr.27-Mar-07 5:11 Ennis Ray Lynch, Jr. 27-Mar-07 5:11  Does not generally write to the console very well, it is binary. If you really want to read it you would base64 encode it to view it. The actually format of the file should be defined by the class that wrote the file. Also a byte goes 0 to 255, printable characters are above 32? I believe.

How to compare password from notepad with in the textbox krajah1027-Mar-07 4:39 krajah10 27-Mar-07 4:39  Question 1form1) How to compare my default password that i save in notepad. How to compare with the password that user input in text box.How to call the password that have key in the notepad. Question 2: In another form I make to textbox one for user input old password and another textbox for user input new password.The new old password will be replace by the new password in the notepad.After this it will compare with the new password in the form1 Tq.Help Needed Re: How to compare password from notepad with in the textbox Christian Graus27-Mar-07 4:44 Christian Graus 27-Mar-07 4:44  notepad is a program. I assume you don't have notepad open ? File.ReadAllText will read the text in a text file, so you can compare it. Why would you store your password in a textfile ? Can you explain what you mean ? Because, notepad has nothing to do with your password, even if it can display it. And, if it can, it's so insecure that there's no point in it existing. What sort of app is it ?

Re: How to compare password from notepad with in the textbox Not Active27-Mar-07 5:16 Not Active 27-Mar-07 5:16  Hash the password when inserting it into the database and compare the hash values, not plain text. Can you use the built in ASP.NET 2.0 login controls? It would save a lot of work on your part. only two letters away from being an asset
