I would like to take blank secure stock paper and convert it in to a check.
I know you can get magnetic toner and print MICR.
The question is What is the actual font to use or should i get a package and send the data to it to print the check?
Has anybody done it successfully without having to resort to pre-printed checks.
I have a class that needs to check for errors in the data contained in a object.The routines that will check for errors could be implemented in concrete interfaces of supertype IErrorCheck. That way error checks can be discrete and added or removed from the class that requests the error checks.Each IErrorCheck implementation would be programmed against the supertype IErrorCheck (Strategy).But it would be nice not to recompile when checks are added or removed.Is there an accepted procedure for abstracting the error checks all the way out of the program, such as to read the checks from a file?

Im confused on how to write a code on checking duplicates before insertion on vb.net. I know the sequence on how to do it but its kinda confusing when writing a code.
1.) Create a query that will check if the mobile number already exists on the database
2.) If not, insert the new data
3.) Else, a message will prompt that "You are already registered".
writing this in PHP is kinda easy for me but in vb.net.. , unfortunately, not easy.. Im still a beginner on vb.net.

I am using a third party OPC library.I have a routine that basically checks that the connection to OPC is active and if not, waits 10 seconds and reinitializes by calling a .disconnect / .connect on the third party library's object.The OPC connection somewhere in its chain is using a com object that dislikes this behavior due to the object belonging to another thread.Ordinarily I would invoke a delegate to get the call back on the correct thread, however this base class does not implement ISSynchronizeInvoke.
Is there another way to make sure a a call to to an objects methods occur on the thread they were created on from within a system.timers.timer which is obviously running on another thread?Error message is: "The application called an interface that was Marshalled for a different thread. (RPC_E_WRONG_THREAD)"I know, kind of vague without a whole LOT of sample code, looking for pointers on where to even begin looking.
This code is supposed to return all the records where the month component of the DateCreated is equal to the specified MonthIssued value. The problem is, if DateCreated is DBNull I will get a runtime exception which requires the extra If ternary operator. Any way around this / will this cause a performance hit the code is actually executed?

View 13 RepliesI have a Check Box that the use checks to indicate that a specific situation is present. When the User checks the box he gets a Message Box reminding him that the condition must be fulfilled. This works fine and the database reflectthe fact that the Check Box is filled.
At a later date, if the user calls this record and fills the form, the Check Box is triggered and the message Box appears in the middle of the form fill operation.
Is there a way to prevent this from happening. I want the Check Box checked but don't want the message box if the change is triggered by the fill process.
I've been trying to create a function that checks if a number is a prime. according to [URL]..I have created a function although It doesn't work as expected.

It sometimes returns true for composite numbers. oh and I know if you google it you get functions that do this, but most of them look inefficient so i'm trying to make my own.
I wanted to create a function that checks to see what button has been clicked on the windows form. For example If I had 10 generic buttons that open up different audio files. I would I create one Sub that can verify which button has been selected. I was either going to use a case statement or an if else. I did not want to create one sub for each button since it would be a lot of duplication in code.

I have 3 different validation groups on my web page, but when I click submit I want all of the groups to validate? It seems to me like the causesValidation="true" of the button will not validate the validators that are in their own validation group. So right now I am calling a javascript function that manually validates the groups.
[Code]...
Now this works fine and dandy... But it seemed to me like before I had all the groups on the page the validators where much faster than how it has to validate them now. Is there something special i have to do to my button to get all of the groups to fire when it is clicked without the help of this javascript function?
Im currently making a tower defense game and im on my last bug for the game and i cannot get it solved. For some reason my For Loop to check if a shot hits a person is not working properly. Ill set it to "For Me.x = 1 To NumOfFaces 'Const for 5' and itll only check the first enemy and last enemy. Here is the code to check for if a shot hits an enemy, this runs on a timer through out the game.

For Me.x = 1 To NumOfFaces

I have a listview with checkboxes on the left side and 2 columns of data. What I want to do is populate a listbox when the user checks a row in the listview. I've tried code in the Item_Check event. It does not pick up the item checked. It's as though it's behind. For example if my listview has a list of country codes and I check US, the code returns nothing but if I check another item, it picks up US. Same thing happens in the SelectedIndexChanged event. If I use a button, all works as expected.

I would like to understand/know how i could have a splash screen which checks a database connection, makes a few calls to other servers and if the criteria meets it loads the default form (otherwise the app exits).
Currently im using the Load method of the splash screen which loads the default form when the criteria isnt met. I looked into the other events (i think under application) but cant get it to work as i require.
I have a datagridview with 3 checkboxes, Yes, No and InV.At runtime, I want the user when he checks one checkbox the other two are unchecked by default. Therefore, at whatever one time ONLY one checkbox will be checked.

im trying to write a program that checks a website if a certain value is within a limit and if not enters a value into a text box and submits the information. I have researched into httpwebrequest however i cannot quite figure out how to progress from page to page. I also found that i can do browser manipulation however I don't a browser to be a open while the program is waiting for a specific value. So is there any way to do something like browser manipulation without the browser?
View 2 RepliesI'm creating a base class for a button that inherits from Control as opposed to ButtonBase.
I'm using reflector to look at ButtonBase to make sure I don't overlook anything important and I'm puzzled with the contents of the WndProc method. There's checks in there for things like button up, click and capture changed, which as far as I can tell are all handled within the relevent 'On' methods of the class.
I'm Trying to make a piece of software where You enter a number and the computer measures the length of the number, and then generates random numbers to match the human number. It will then count the number of guesses and the time taken. However it always comes up that there was a infinite loop "An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll". I have searched up how to do this and I can't seem to find out how. I think I just put my wording wrong when looking it up.

Here is the Code:

Dim GuessesTaken As Integer
