I need to know how create a number that increases every time my main form is loaded. This would go in succession. So the first time after putting this code in it would show the number 1. The second time I open my main form it would show a number 2, and so on.
View 2 RepliesI'm not sure where to start. I've made an app consisting of a textbox and picture box that changes the picture every time you press a key. But what I need is to load a txt file and have pictures display one after another for each letter at a user defined rate. Including breaking this down into smaller steps. This is for an application simular to a RSVP(rapid serial visual presentation) program.

I'm trying to give some user tips when they load my application.
I am just a beginner in vb .net. I am now developing a window-based software.This is the problem:
1. After the user log-in, the system must show the parent form and automatically show the main transaction form base on the user role or user accessibility in my system manager. Is it possible to do this?
2. In my menulist, I need to recognize which menulist.item is selected. So, I need to bold the letter of the selected menulist.item or underline the word.
I have a little problem, nothing very serious, but something that anoys me and i can�t solve.
I have a VB.NET windows form project, with a main MDI form containing a menu.
I load all forms with:
Private Sub MostrarFormulario(ByRef formulario As Form)
Try
formulario.MdiParent = Me
formulario.BackgroundImage = Me.BackgroundImage
formulario.BackgroundImageLayout = Me.BackgroundImageLayout
[Code]...
When show the form, i can see all combos / grids / objects being placed and feeded. Its a fraction of second (in fast machines). All my objects placing and loading are made in the Activated event.(because some combos data may have been added/deleted and the app can have multiples form oppened at the same time).
Is there a method for loading everything first (not showing) and then display all at the same time?
How do i get my first item to show in combo box when form has loaded?

View 9 RepliesIn an attempt to learn VB I'm trying to build a database project for a friend's business. This db will be used to track customer information, predominantly for targeted marketing purposes. So far, the development has been slow (I'm still trying to adapt from VBA to VB), but its all starting to make sense now. I'm using two different forms for adding new customers and reviewing the information of existing customers, mainly because the database will grow by about 2,500 customers per year and we wanted to be able to search the records without returning every record when the forms load. Most of this works so far, but I'm having trouble with two issues.
When I open the new customer entry form, I want the form to automatically begin entering data without clicking the "Add New" button. The second problem involves the row ID from the database. It keep showing up as "-1", "-2" etc. The row ID records properly in the table, so no big deal. I have read that this problem is a bug in VB and that its nothing to worry about. However, down the road I will need to access the correct row ID from this same form in order to print out a report for the customer (as needed).
For what its worth here is the code I have so far:
Code:
'Update current record when the form closes
Private Sub frmNewCustomer_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.TblCustomersBindingSource.EndEdit()
Me.TblCustomersTableAdapter.Update(Me.dsNewCustomer.tblCustomers)
[Code] .....
how I can load another form when a condition is met? I want to load form Result.vb when the lblQuestionCount reaches 5. Can anyone tell me how to do this?
View 9 RepliesI wrote last week about a problem with an MDI program that had a large number of forms (each with a large number of controls on it) that was "sluggish" in loading and in switching between the child forms.I've attached an example program in VS2008 (though the actual app is VB2010)Rather than show the hardware control application with all of the text fields, and picture boxes acting as indicators, I made a simple program to show the point. This is exaggerated as this just loads 2000 or so text boxes on a form. In the real app I have ~ 200 assorted controls per form of picture boxes, scroll bars, text boxes, labels etc. Also, there is a large full screen .jpeg as the back ground of each form. All are generated at run time and are placed on the form in the New call of each form. (as in the sample attached)main issue seems to be the methodology I use to switch between child forms. I make the current form .visible = false, and the next.visible = true. I have used this as it "keeps the place" on each page if the user has scrolled or is looking at one section of the form. When the next form .visible = true happens I see the controls added in a "machine gun" fashion instead of all at once.
View 28 RepliesI have an Access 2007 (w/ Vista O/S) project where I use an unbound form, to populate the form I use a DAO recordset to pull the data from the backend table. I want to have the ability to load a project and return the attachments that are only for that particular record. Subsequently, I need to be able to save any attachments to that project record when the 'Save' button is clicked (the files to be saved to the record are user-defined, and therefore not in a particular/ constant folder).
I would like to avoid using OLE objects and streams if possible, but not sure if that's doable. I know how to navigate to the given record, but how do I return the attachments? Also, I've read this article [URL] and a bunch more, including other MSDN articles [URL] and their related links and still not sure how to achieve the desired end result. I've also tried changing the attachment object's (located on the unbound form) controlsource, but to no success.

I need to determine if a set of keys have been pressed in succession. For example, if I'm looking for this combination: Up, Up, Left, Space, then any key that inteferes with the order would start it over.
I tried doing a basic test to see if it would be as straight forward as I was hoping:
VB.NET
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
If e.KeyCode = Keys.Up Then

For some reason, it doesn't let me continue the sequence. I put a MessageBox on the second "Up" and it triggered when I pressed it just once.
I'm writing a program for my algebra students to practice integers.Stuff like....
3-6
-4 + (-5)
3(-4)
-15 � 3
etc.
I want to show an explanation and for the addition and subtraction, I want to show it on a number line. For example, if the problem is 3 - 7, the number line should show and arrow to that goes right to 3, and then left 7 units (starting from 3). Then the student can see that the answer is -4.I could probably do this with some string manipulation, but what would be the easiest way to do it in a picture format? Maybe a bitmap.
In VB if you prompt the user for a number between 1-20, then a word, how do you get a text box to show the word the same number of time as the number selected using loops?... Ex: please select a number: 4 / select a word: cat....the text box should display ::: catcatcatcat ........

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
