I have created an application which consists of 3 Layers: GUI-BLL-DLL. When I am loading a flat file I am doing this in the DLL but I want to show to the user the process through a progress bar in the GUI. So I want to pass the variable LineCounts from the DLL to GUI. I know that I have to use EVENTS

View 2 RepliesI'm trying to program in a true object oriented manner and its causing me to re-learn a few things. Specifically, I'm having some trouble with error handling. I have all of my data access being performed by an adapter class in a seperate project. I can catch duplicate records without any problems, but I want to be able to send a message back to the user. Here's what I have so far:

I have two tables:
table1
case_no flow result
tc_1 001 pass
tc_1 002 pass
tc_1 003 pass
tc_2 001 pass
tc_2 002 fail
tc_2 003 pass
table2"
case_no result
tc_1 pass
tc_2 fail
Table2 should be updates from table based on the results... If all results is PASS then the table2 should be updated as pass... if any result is FAIL then the entire case_no should be updates a s fail..
This code was working consistently, but now...This code works on the first pass.Then second pass it just hangs on Code:Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() for about 2 minutesThen the code will fork for another pass, then fail.....

Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.

just curious if there was a way to make the text in a message box scroll across the message box
View 1 RepliesI am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

I'm making a simple decoder. Type a message in the "message" text box and it spits out a code in the "code" text box. If you pop a code into the "code" text box it spits out the message in the "message" text box. Seems simple, right? Well here's my problem. I typed "The quick brown fox jumped over the lazy dog" to test it and it will put a lowercase "f" at the beginning, put letters that aren't supposed to be in there in there, and replace what should be upper case letters with lower case. I commented out the code for replacing symbols because it seemed to work fine before I put them in the code but still the same result. I checked over the code to see if I mixed stuff up. Like I accidentally put the replacement for a lower case "e" as the replacement for a lower case "h" but I can't find anything.

But in my application i need to pass the ID of my Client (company) to fecth it's businessName. So first i've written a storedprocedure to return it's ClientID searched by BusinessName, then i pass the ClientID to fetch all the other details of the client such has his contatcs...etc....
Therefore currently i use two stored procedures to one i pass the businessName then i will return it;s ClientID then to the other i pass the ClientID then it will return everything about the client (beucase client was indexed on clientID)
Is it possible to write only one stored procedure to perform the two operations..

ok to start i know very little about VB6 but i am very good in true basic lol (stupid school teaching the wrong language -_-) anyway im just asking you to make the answer as clear as possible because i don't know very much. heres the problem . ok in the above example i have a button that (for my example) can be used to build a house (lol) i then have a variable in the button sub called money which will have 150 subtracted from it when the button is clicked my problem is it say variable not defined when using this button ... i have declared the variable in a module and in form load along with my other 50 or so variables. my question is how do i pass the variable into this sub and then send the new value back into form load so it can be sent into another sub for more calculations.
