hi all, am new to C# programming and i got a little problem. i made a windows application form used for login to another form, it has "username" & "password" text boxes. it's connected to an Access database which stores the authorized usernames & passwords, so what i want is when the user clicks the "login" button..the program should check the user input whether it's found in the database, then it can tell user "access granted" or "access denied". thnx in advance

i got an application that contains a text box, i want to draw lines depending on the TextBox input. I know how to draw, but how could I make the drawings dependent on TextBox input. thnx in advance

i am developing an application for my final year project, that generate barcodes. my problem is that i want to tell the program to draw a black bar when I enter the number "1" for example, or two black bars when I enter "2"...etc. Could anyone help ?! Thanks in advance

thnx for ur help, one more thing, could I determine which data type could be entered in the text box, i.e. if the user entered "floating" no. for example it doesn't move the cursor. The user should enter "integer" for the cursor to move to the nexr text box.

thnx a lot man. but am sorry i got another question, this two lines of code counts the number of words only in case they got only one space character between each two words, what about if i got a sentence like this "hello world" with 5 space characters for example and not "hello world" with one space character. the program won't count the first sentence as two words i think.

simply, i want to make a c# program that counts words in a sentence entered by the user. i know a method to count no. of characters in a certain sentence, but what about words, what's the idea ?! i'd appreciate it if anyone could help here.
