I want to show a dialog box or form immediately after my application loads. If I place a .showdialog in the main form load event the dialog shows before the application shows.
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?

I found this mystifying in VB6 and it's still here...
For example - I have a combobox on a form and I have put some code in its SelectedIndexChanged event. The problem is that I want this code to be executed *only* when the user clicks on an item in the combobox dropdown. Why is it then that it gets executed when the form first loads? And how do I stop this happening?
I used to use a "FormLoading" boolean to decide whether or not the code was executed but this surely shouldn't be necessary. Is there a better way?

The problem im having is that DotNetBar gets referenced fine and all the controls appear in the tab but when i drag one from the toolbox to the form it stays in the panel where usually the timers and other controls are..Example : Drag a ButtonX from DotNet toolbox tab and it goes to where timers and dialogs usually appear instead of on the form.The standard default controls work fine. But seeing as i already have 60-70% of my application done with DotNetBar controls, I am receiving errors like frmMain.chkboxx cannot be accessed as its private.I was working on my laptop and decided to install VS2010 to Desktop and Copy/Paste the whole project folder over and this happens (I can still open the project on the laptop fine and DoTNetBar works)[code]

I have a form-based application, that until recently displayed the controls on the form when in Design. For the last week or so, when I go to Design mode for the form, it is blank. However, the program does work correctly. And, I can see the control definitions in form.designer.vb. How can I get my form to display the controls again so I can add/move/change it going forward?

I 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.

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.

I have a couple of user controls, which I show in my main form.
So let's say here's what i want:
Sub Show_Control1()
UserControl1.Show
'CODE TO HIDE EVERY OTHER DISPLAYED USER CONTROL ON THE MAIN FORM
End sub
Right now I have to hide them one by one with hide, because I don't know what's the current displayed form.

In 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)

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.

I have on a form a UserControl that I use as a Data-Entry form. I show and hide it constantly with new data. Often (not all the times) the same two memo-boxes are shown on the screen first for a second, and then the full control is visible. I found this link, I'm not sure if that's my solution, but in any case I don't know where to call it and when. EDIT: I noticed that it happens 'only' if the program is idle for a couple of minutes. I could show and hide the control 10 times one after the other no problem. but if I hide it and show it again after 2-3 minutes then I get this behavior.
I guess it has to do with the time it takes to reconnect to the MsSQL database to pull the data. But how can I tell this 2 boxes to stay invisible like there parent until the parent is ready to show?

I am performing a migration on a vb6 program, to vb.net. The basic knowledge you need to understand this question is that there are two forms that need to talk to each other, frmInput1 and frmInput2. I have the following code (behind frmInput1) that checks if a textbox on frmInput2 has a certain value, seemingly before it has loaded:

This is an odd question but can I load custom controls from a directory? (e.g TestControl.dll) in my application at runtime instead of adding a com reference?The reason I am asking is that I have an application that is installed as an add-in for MS office. The entire interface is a panel that contains a user control. Initial installation is a bit involved so after the first install, I would like to use clickOnce to deploy updates by just supplying new user controls.

I have very strange problem, here it is: I have a quite large MS Access Database (2003) containing exactly 68020 records (rows). The problem is, when i read the entire database directly toa data representation control like DataGridView or Listbox,only 66710 records are returned. The weird thing is: If i load the entire database to a in-memory datatable object, rows.count gives "correct" amount of records as expected, that is 68020What is the reason of that? Why DataGridView or other controls cannot have records more than 66710 items? Is there an internal limitation? (That's dread if there is).

I am currently wokring on a project, which is going to serve as an interface for accessing various documentation and reports. It is basically just a tabcontrol with a few pages that will be poppulated with buttons which will open the appropriate document.I am trying to allow administrative users the ability to add new, edit or remove buttons which all seems relatiively simple, but have run into the problem of how to persist the changes once they are made. I want the setting to be stored centrally, either in a SQL table or on a network share

I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.
