I'm trying to make a program that takes my old records from Access and moves them to MySQL. Its supposed to take records from 3 different tables in Access to 3 different tables in MySQL. The first table is "Orders" and it sorts the ones to pull to the dataset, taxDS, by "Where Status = 'Waiting Payment' OR 'Cancelled'". Then the second table pulls its info(this is where i'm having trouble) by the "Control_Number" in the "Orders" table, so basically if the control number isnt already in the dataset its not going to pull the data into the new table "FNF Taxes".
Imports System.Data.OleDb

View 3 RepliesI've recently started programming for Visual Basic Express - 2008, and I'm currently trying to make a program which takes a bunch of inputs (Name, Age, x2 score results) and then turns this into an output at the end which varies depending on the score results.
I've stumbled upon a small hinderance, which is that the very final stage which has a Console.Writeline does not appear after testing the program. So, everything else functions fine, but as soon as it gets past the "Console.WriteLine("All pupils have been calculated, the results are...")" command the program closes itself.I'm not looking for much help, just wondering exactly what is causing this to happen. I also realise that my coding is sub-par and is coded in a slightly odd fashion, but I'd rather just get this one to work and use the mistakes from this one to correct my future work.

im asking for help on how to Make Folder and it name by current Date?
sample today is 11-08-2011
so program will create a folder name 11-08-2011 (Nov.08,2011)
and also creation of folder triggered by timer lets say Folder creation every 11pm daily.
I would like to calculate a new date simply by using the build-in dateadd function, but take into account that only weekdays should be counted (or 'business days' so to speak).I have come up with this simple algorithm, which does not bother about holidays and such. I have tested this with some simple dates, but would like some input if this can be done in better ways.This sample assumes a week with 5 business days, monday-friday, where first day of the week is monday. Dateformatting used here is d-m-yyyy, the sample calculates with a startdate of october 1, 2009.
Here is the simple form:
Dim d_StartDate As DateTime = "1-10-2009"
Dim i_NumberOfDays As Integer = 12
Dim i_CalculateNumberOfDays As Integer

I need some help in the creation of a program to generate a security code based on the current date. I need to create something that first multiplies the MMDDYY (ie X=MM * DD * YY) then also adds the MMDDYY then finds the remainder and then multiplies but a specified number. I would like to create a small program that sits in the system tray with this code displayed. The code will always need to be 6 characters, so I might need to pad it with zeros. It has been years since I took basic VB, and I am really rusty.

I'm fairly new to ASP.NET & VB.I've been asked to take an existing textbox that is automatically filled with the current date and allow the user to either add a "+" or "-" and a number or a spcific number and convert that into a date.I underdstand the basic concept on how to do this, but I'm running into some problems using the proper commands in order for this to work.The Textbox is called txtDate.What I've tried to do is this:
If txtDate = '+' Or '-' Then
DateAdd("d", txtDate, today)
End If
Here is what the whole thing looks like:

View 1 RepliesI have a field called PODate & TextBox txtPODate.text. It saves/updates fine when the txtPODate is filled. But when the txtPODate is blank, it throws an error. The problem is that I can't enter date for each record unless I got Purchase requisition converted into Purchase Order. Once it is converted to PO, I need to enter the date to update that filed. So, how can I make my program to accept blank date field.

View 1 RepliesA couple days, I figured up a working program and it was def. faster than what we needed. Now, adding a couple more loops, the program barely uses any memory, but the cpu used spikes up to 90+ and just letting it sit doesn't help.I tried taking out the couple loops I put in, but it does not revert back to being fast. It's nothing big, but since dealing with 1000+ excel files a day, I'd rather not do that by hand.
how many infinite loops vb.net can support without dragging down the system? I know, infinite loops are poor design, but it works.
in my program i have a timer, and every 5 sec (for example) i send a string by serial.i have to read every key pressed between each 5 sec and send a number that tells me what i am sending.what I've done is to send 1 as long as up key is pressed and send 8 as long as left key is pressed and send 9 as long as both are pressed.when i run my program, the first time i press up and left at the same time and i keep them pressed, the serial send me the first time 9 and then ignores the up key and send me 8 always.and sometimes send me 9 and after that always send me 1 and ignores the left key..the point is that vb ignores the first button i press even if i keep pressing it..what should i do to make vb.net takes two arrows keys at the same time?

This is probably a stupid question, but how do you make a function which takes a number then does an operation to it again and again until it gets a vlue which it already has seen, when it returns all of its values? I have this function:

Fractal = Val(D) * (Val(D) - 1)

I am not recieving any errors, but the program is not doing what I had expected. I wish to make a program that randomly takes characters (well, not completely randomly. I used the table of letter frequency from wikipedia and included that data in my program by figuring out the max for the random numbers from the percentages in the wikipedia chart.) and adds them to a long list of characters ands saves the file every 5 minutes. I have calculated the timer interval so that the number of miliseconds shown is equal to 5 minutes. I am getting the textwindow, and it is showing (rather rapidly, as I need it to be) a long random list of characters (including spaces). The problems are (A) I am having difficulty saving the text as a file. You'll find the code that is supposed to do that at the bottom. The other problem I am having is once so many characters are added, the ones at the top start disappearing. I would scroll to the top, and each time I did so the letters at the top had changed (this is all during the same test), but I need all characters to be stored when the file saves. Granted, I haven't actually seen one of the saved files as I have not figured out how to make that work. One other thing, not sure if it's important, I haven't run a published version yet. I've only been running the debug builds. Does that affect how it handles actions with files?

I've been working on a program that takes input from a textbox, removes the punctuation, puts the words into an array (using the split method), and compares the array against a reversed copy of itself to determine if it is a word palindrome or not. I understand the logic, but I'm getting kind of caught up as far as what code to us. This is what I have so far, but no matter what I enter into the text box, nothing happens. I'm completely lost as to what I'm doing wrong.

I'm writing a program which takes one item from each of two lists and combines the items in one of three ways selected by the user. The results of the process are provided in either a summary form or a detailed form, again selected by the user. As it's currently developing, this program will contain six subroutines covering each of the six combinations of user selections, which are stored in three Booleans. Selection of the appropriate subroutine is done through traditional "if then else" coding.If I understand OO and Visual Basic (Express 2008) correctly, I could make the subroutines into different variations of one method, which when invoked would automagically use the correct coding depending upon the settings of the Booleans / properties. Assuming this is correct, the problem is that I have no idea how to actually set up code like this.
View 4 RepliesI have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?
