VS 2010 Load Form But Don't Display It
Jun 12, 2012
I have an app where there's an edit form and it loads a bunch of stuff into comboboxes which takes half a minute to load the first time. Once it's loaded I keep the instance of the form and just hide it instead of disposing it until the app exits. What I would like to do is in the Sub Main of the app (there is no startup form) I would like to launch a new thread and load that form into memory, but I don't want the form to be displayed at that time, what's the best way to do this?

I want to pre-load a number of images from the web, so that I can display them in a form, and scroll through them without delay. It can be a large number, but i only need to pre-load perhaps 20, and then remove/add in advance, as I scroll through. The images will typically be .GIF or .PNG, of quite small size, <50kb. The link for any single image will look something like this: [URL]..and I will keep a list of all the links I need to access.
What "type" shall I use to store these images? And how do I make web requests to put the data into this type? I guess it will be more convenient to keep this as in-code list of some memorystream type (?) instead of saving them to disk and having to deal with file names and stuff..? Also, what type of control shall I use to display such images? Do I use a PictureBox?And if a memorystream is indeed the best choice, how do I make this show in the picturebox?

I need a way to allow another form to load after my program display's an introduction cut-scene without loading the form in the middle of the cut-scene. Sort of like a delay.

I have a code which when used, firstly application will run the Splash Screen application. Splash Screen will be active for several second, and then the main of application will show in full screen. Before the user use the application, user must Log in first. This works but the problem is that it loads the splash and login form twice. To worsen the situation, the second login form that appears gives access to the system even when the cancel button is clicked while the first login form just works fine. My codes for the three forms are as listed below:

Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.

I have a form in design view and when the form loads, I want the TimeMaskedTextBox to show the time now. But allow the user to change the time for later time in the day.
Let's say the time now is: 09:00 and the user wishes to change time to: 22:00 and when the form is saved, And a new form is loaded then the TimeMaskedTextBox will go back to the time now. How would the code be written.

so I have the following
Try
Dim username as String = My.Application.CommandLineArgs(0)
Dim password as String = My.Application.CommandLineArgs(1)
Catch
Msgbox("Cannot launch")
Application.Exit
Exit Sub
End Try
I placed this in the form's load event. What I want is for this check to run before the form even loads.If an error occurs, the msgbox comes up and the form is never seen. When I try the code now, the form comes up the msgbox shows. When the user clicks OK the form closes. I tried placing it in the form's designer but the designer tries loading the form any way. How do I get this check to run before the form shows?

I am making the Transition to VB.Net (using VB.NET 2010 express) and I have a simple problem that is driving me crazy. I wish for my Form when it Loads, initialise and then call a sub and do some stuff eg perform a plot. If i place a button on the form and click it the sub works fine.This task was simple to do in VB6 but for the life of me I cannot get it to work in VB.NET. Has the Form-Load event changed in some way with .Net?

I have a calculation project with 6 forms. The last form shows all the input and output data from the previous forms. This is accomplished in form6 load event. Form6 contains about 40 controls (mostly textboxes, labels and few pictureboxes), populated in this way:Textbox1.Text = Form2.Textbox3.Text, etc.I am not sure if this is a good practice. I know I can use the DGV, but it does not suit me because of the graphical reasons.

What I was thinking of is load a webbrowser window somewhere in the form, but within the webbrowser size, by default, load only say the Half left (or right) part of the webbrowser window. In pseudocode it would be smth like webbrowser1.show(1*webbrowserWindow.Height, 0.5*webbrowserWindow.Width, webbrowserWindow.With.StartFromLeft/Right). Now I know it sounds pretty crazy, but it would be smth very handful for me. Look at the SS below if you didn't get what I'm trying to say because that's quite possibly as clear as I can be.

I have set up a form that will act as my parent (this hasnt been set up as an MDI).On this form I have a Panel that I will be loading forms into. I have a form that contains a DGV. On the load of the parent form, I then load this "child" form into the Panel. In the onLoad event of the "child" I go off to the database and populate my DGV. Then I run through the rows in the DGV and add in a logo image in the first column and change some cell colors based on values in those cells.
This all works great, however, when the child form finishes loading all the changes are lost. eg The logo images go back to the red cross and the cell coloring is gone.If I call Me.Refresh() in the child window as the last line in its Form_load event I can see the logo and cell colors update to what I want, but as soon as it has updated, its like it immediately refreshes again and all the changes are gone.

I wanted to select the row the user was last working on in the datagridview. So I created a setting to contain the row index. But then I had trouble using the form load event to select that row in my datagridview. It would always select the first row. I then moved the code into the DataBindingComplete event and it worked like a charm Example:
Private Sub dgvTaskList_DataBindingComplete(sender As Object, e As System.Windows.Forms.DataGridViewBindingCompleteEventArgs) Handles dgvTaskList.DataBindingComplete
[code]....
PS, if you want to select the full row, make sure the DataGridView Selection Mode property is set to FullRowSelect.

I have a very large program I would like to write but think starting with a smaller test program would be a good idea. What I want to know is: I have a base Form from which a user clicks a button to answer a question (Answer A, B, C, or D) which if the answer is correct will pop up a "Correct! answer response in a separate window. This is ok for now, however, when the "proceed to next question" button is clicked, I would like the next question to appear in the original base form window.
Right now it pops up in a separate window and I'd rather not have 20 windows open at the end of the quiz. How do I load the next form in the same window!? Obviously it's possible and could be something I'm completely overlooking, and I've also read that I could replace all data with the next Form. I have searched "Visual Basic load form in same window" and came up with results, but none of what I'm looking for.

In trying to test some graphic features, I am trying to get them to display on load so button doesn't have to be pressed. I used the following code as suggested from forum. Message boxes run but ellipses aren't displayed until button is clicked which is what I am trying to avoid!
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Button1.PerformClick()
Button1_Click(Nothing, Nothing)

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 created a windows form which contains a datagridview. I named one of the columns in the grid 'location' which appears to have generated an error. The problem is I cannot load the form to remove the column as an error is generated and when I load the designer code it says do not modify with the code editor but use the windows form designer.

This is the strangest thing, I can not figure out why this is happening. When I delete a radio button from my form which is used to filter data in a database Form_Load stops working.My project consists of a database and a web browser. The database has a search filter options.[code]For some reason it didnt load my settings on start up. I made a button which displayed True/False in a text box to check if it was saved in my settings, it was, it just didnt want to load. So I deleted it and everything broke! Nothing in the code is referenced to the RadioButton or its code.
Have I done something wrong or is VB just messing with me? There is obviously a bunch of more code, I just posted what I think is relevant to the issue. If you feel something is missing, tell me and Ill post it. ied to change the RadioButton with a CheckBox, and I changed the code from "Me.ExampleTableAdapter.FilterHide..." to "Me.Example TableAdapter. Fill...", which is the same as in Form_Load. It works if it starts checked. If I remove this code or delete the CheckBox nothing works even though the same code is in Form_Load. If I start off with the CheckBox in an Unchecked state nothing loads, if I check it everything except the Browser works for some reason.

I've decided to learn Visual Basic .Net as this is what some of my colleagues work with, and this will allow me to work with them on projects.I have purchased Microsoft Visual Basic 2010 Step by Step and downloaded the sample files. When I am trying to debug the first sample application (a Windows form), it is telling me that it can't load System.Drawing V4.0.0.0. However, if I create a new Windows Form application (C# or VB.Net) this works fine.
I had a look at the References tab in the project settings and System.Windows.Forms is referenced, but the version referenced is 2.0.0.0. I have removed and re-added this reference and it stays at 2.0.0.0 and I still get the error.Does anybody have any ideas as to what may be going on?

I have a text box in form1 that displays the total, I want to carry this over to form 2 into another text box as I navigate between them, how would I do this? Also I have a button on form2 to return to form1 but I need all the data that has been input by the end user to be cleared from both forms when returning, again how would this be completed?

I'm using VB 2010, accessing a MS Access database. I have constructed a simple Windows Form returning data from the db, one field of which has a reference to an image I'm trying to display together with the data from each individual record.
I have a field with a product number, that matches the jpg file name (ie, the product number 5505 matches an image that I want to display, namely 5505.jpg). I've even created a new field in the db called 'Image', that contains the full name 5505.jpg.
So, I've connected to the db with an OleDbAdapter, and all the data fields are displayed via bound textboxes. I've been able to display a single 'set' image with a PictureBox, but I'm not sure how the make the connection between the returned data (txtSearchImage which is, say, '5505.jpg'), and getting the Windows Form to display this.
Am I on the right track using a PictureBox? I've tried binding this via the PictureBox properties to the relevant data field, but (obviously) it doesn't make the connection to the image file on my hard drive.
Here's my code so far:
Public Class Form1
Private Sub btnSearchKits_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchKits.Click
' The following line passes the value the user enter for state
[Code].....
