View 6 RepliesI am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

I have a few SQL connected check boxes in my form.The problem is that on the 'Add New' event the check boxes go into a "intermediate" status (filled in).What I would like is for all the check boxes to be unchecked.I have so far tried the following and none of it worked.[code]Nothing seems to help, in fact there seems to be no effect at all on the check box properties no matter what I do (wether I change the property in VB, in the table definition, or programicaly).

View 2 RepliesSo I have an .aspx page loading up and populating drop downs based on a lookup table in the database. What we want is for the user to be able to configure which of these values comes defaulted by specifying that value in a drop down somewhere else in the app. Now, it's easy to default the "first" value, or something like that, but we want this to act differently. Is there a JavaScript function that can run immediately after onLoad (so the drop downs are populated already), that can go through the drop down and make one of those default so it looks like the page is loading with that set as default and people don't realize the workaround? (weird masking, etc.)
Here is an example of how we add the dropdown control to the page:
With CType(.AddControl(New Controls.ComboBox("CodeId", "../../../../CodeId", "Code")), Controls.ComboBox)
.ForceSelection = True
.ValueField = "LookupID"
.DisplayField = "LookupDesc"
.Validate.AllowBlank = False
.ForceSelection = True
.ReadOnly = EditControl.IsFieldReadOnly(10580)
.BindData(Model.Codes)
End With

View 1 RepliesI have a form that has many controls. My next task is to populate the phone number (MaskedTextBox) and phone number type (ComboBox) when the cursor has lost focus from a ComboBox that has auto complete functionality. I have tried to do it and when the cursor leaves focus, the other controls are not populated. Nothing happens. I do not get any errors either. Screen shot attached for the form and I am also using a stored procedure to do this. There are two tables in question here. A client table that the name and phone number and then the second table that has the phone number type (cell, work, home, etc).There is an FK relationship between the two.
This is my stored procedure. It is called sp_GetClientInfoByName.

CREATE PROCEDURE sp_GetClientInfoByName

"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?

I hope this is the correct place to obtain a little bit of advice for a program I am looking to produce in visual basic 2010.
I currently work as a design engineer designing press tools and a lot of our designs are similer just maybe a feature, length, diameter change etc. So the design principles are the same for each product.
What I am aiming to do is program the 3D design package so that 80% of the tool design can be done using the program etc.
Now the enquiry I have is where would the best place to hold the standard data be?
For instance each press has a maximum blank diameter, shutt height, bores diameters in the bed and likewise each product type has design features with the same calculations such as length, pierce etc.
I have done a bit of reading and I have found that data can be stored into text files, xml files and databases etc or hard coded into the program.
I am looking to allow new presses to be added so the user would need to add new shutt heuights, blank size etc but the tooling would have to be unqiue dependent on the typs of stage. So I am wondering to store this information would a database be the best option even though the data will not be continually updated more a place for it to be retrived from excpet under failry rare circumstances.

I have a VB.Net app that uses an MS Access 2003 Database. In my connection string, I'm utilizing the "|DATADIRECTORY|" construct (see code). cnn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DATADIRECTORY|MyDB.mdb;User Id=;Password=;"When I run my program, I'm getting the following error message:"Could not find file 'C:indebugMyDB.mdb'"
In order to use the "|DATADIRECTORY|", where do I need to put it within my Project. I basically want to deploy this app on stand-alone PC's. I guess a more simpler question would be: How do I deploy a single user application that uses an Access Database where the database location will go wherever the user specifies when installing the application?
