Forms :: How To Make A Windows Form More Responsive
Aug 5, 2010
In my (VB.Net+VS2008) application, I want to make my windows form (splash) more responsive as there is some complex functionality is performing while loading splash form. Currently when any other application come in front of splash screen and then minimize then splash screen looses its proper visibility and showing some hang kind of state also.
I used Application.DoEvents(), but it doesnt work. I cant use background worker because it doesnt support UI related changes. i.e. Initializing some UI components on shown event of splash screen.

I'm trying to create a child form that helps the user to enter data for a field in the parent form. I want this child form to be modal, but I don't know what I need to do to make this form modal. Perhaps there's a different type of item I need to use; if so,
I'm using VB 2010 and simply want to have a button on the form that says Minimize.I want the form to minimize to the task bar or the notification section .I've looked at other ideas, but the code is for prior versions of VB (2003 and 2005) and some for C #Could you please email me some sample code to handle this?
I would like to know if its possible to start up a second windows forms inside the parent form. Ex: A button is pressed and a new form is showed. I would like to keep that new form inside the parent form, and have it not be able to go outside the parent form.
When I add a new, empty form to my VB.NET VS9 project, the linenherits System.Windows.Forms.Formis missing.What am I doing wrong here?I thought it would be added automatically.I experienced that some thing get weird if this line is not there (Form_Load is not firing, I think).
I'm upgrading a project from VB6 to VB2008.I have a routine that clears a combo box, named 'cmbDataTable' which could be on any form. I pass the form and the combo box is cleared.
[code]...
I assumed it would be the same in VB2008 but I get the error.'cmbDataTable' is not a menber of 'System.Windows.Forms.Form'I am working my way through the project, first updating the global procedures - this is one - I haven't written the calls so cmbDataTable doesn't yet exist.
I like to know how to make the forms buttons and text and data... auto adjust when windows Maximize or minimaze..because when its big I can see everything fine and when I restore to a smaller window the buttons are on the bottom and cant see them... Basically I want everything to look in the same position whether its a small window or big or at least that it has scroolbars if I see it small.
I'm making a program like PostIt! Well, i want to make a model form, and copy that form as many times i want.I think it works with something like frmPostit1 = frmModel.clone()
how to pass value from one form into another form...? for example if i have 1 mdiform and 2 form (form1, and form2) for load form1 i'm using system.reflection.assembly here is the code for load form1 :
Imports System.Reflection Private Asm As Assembly Private FrmNama As Form Public Function GetForm(ByVal FormName As String) As Form
[code]....
after form1 load i call form2 from form1 and from form2 i want pass value, here is the code from form2 to pass value into form1 :
form1.textbox1.text = textform2.text
why value from form2 can't fill into textbox1 in form1?
How can I add a scrollbar to my form I tried the auto scrollbar option but is not working ?? Q2 How can I validate the user inpute inside a textbox to check that he type the desired word?? for Example validate if the user typed the word ( Bob)?
I have a windows form that is set up like one big calendar for the month of may.when you click on May 1st...another form (form2) opens up with some combo boxes and a datagridView on it. What I need to do is on Form 1 (my calendar form)when you click on May 2nd...I want to open a duplicate form 2..the one with all the combo boxes on it.do I have to make 30 duplicate forms ( for 31 days of May)or is there an easier way to make sure that when the user clicks on May2...they dont get a form filled with May1 stuff.I can see that there is going to be a problem as it sits now because I am going to be adding to form 2 some kind of date box, or a date field in my gridview..So I need each form to display the right date?
I have two windows forms,say frm1 and frm2. I have to open frm2 from frm1 and frm1 from frm2.when one form opens other hide. But the the problem is that everytime when i open the form new object of the form is created which increase the memory usage of the application.What should be the efficient way to switch from one window form to another in vb.net.
I created a new windows form application using VB 2010. I added no controls to the form. This is right "out of the box" app created by the VB windows form app wizard. I next added a FormClosed event handler. The handler gets called whenever I click the "x" on the form.Later I needed to close the form programatically in response to an event from an automation client. So I did something apparently farily dumb. I called "Me.Close()" Nothing happens. The form stays up on the screen. My FormClosed event handler is NOT called.The MSDN entry for "Close" doesn't give me a clue as to why this call doesn't work. Indeed, it seems to imply it should work.So I added a couple of lines of code after calling "Close()" since when I stepped across that line of code it appears that no other code would execute. Sure enough, as soon as I step over the call to Close(), I cannot step through any other lines of code.
Then I found another piece of form code while searching around and I found the code had what appeared to be an odd keyword just dangling in the code. The keyword, colored by the IDE as a VB keyword?So I typed "End" into my method and intellisense shows me "End Statement. Stops execution immediately". And it does. But is my FormClosed event handler called. No.I added "Inherits System.Windows.Forms.Form" to see if that had any effect. No change.So how does a form close itself programatically?
I want to make a form which is pop up in window. so, user can not do anything with this form displays. If user close this form, so user can open explorer or . . .. .In all, I want to make a form which pop up like shutdown menu in Microsoft Window, so user cannot click any place beside this form.
I have a small program that works just fine on my desktop (23 inch monitor). I programmed it on this computer as well. My laptop (17 inch monitor) works fine also, however, on a 15 inch monitor the picturebox's are off and not where they were when I programmed it. Also, some forms you can not see the entire form and the bottom is cut off.
How to make a Windows form appear on top of anything? even fullscreen games?I am working on a toolbox like application for one of my favourite games...At the moment it's eluding me, setting the form as top-most doesn't seem to work.
I am working on an application and I want the user to be able to enter commands into a textbox, and when they press enter, the command is printed in a rich text box, executed, and the output is printed. For instance: the user types move{file1}, {location} into the text box and this happens:
>command: move{file1}, {location} >$ moving file1 to location >job completed
How would I write lines to the rtb and execute commands when the enter key is pressed?
This works, partly. Private Sub TextBox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles command.KeyPress If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then RichTextBox2.Text = Environment.NewLine + command.Text End If End Sub
it erases everything in the textbox before adding the line... I would also like to be able to make a database of commands, maybe a .dll or something, so that when the user types in something, it checks that database to see if the command exists, if it does it executes, if not, error.
I am trying to create a basic windows form on VS2008. I dont see intializecomponent() method in my form. Also, I added a few controls on to the forms and set few properties for those controls on design view. Where is that code getting stored?? it isnt on the code behind file.
I know thr is no html code behind file for window forms?? also, where is intializecomponent method. Please help me out. I have been trying to find this out for such a long time now.
I am currently creating an application which monitors any errors that occur in the other applications I have developed.
One thing that I want to try and do is add a sort of discussion thread into the form, so this allows for each member of IT to add comments/notes about the error that occurred.
Normally I would just use a DataGridView or a ListView, but I would like to have the capability for the comments/notes to be multi-lined so that the user can see what has been written without having to scroll sideways.
I use the code about video capture of this site, it ran very well ! VB Helper: HowTo: Capture video from a video device such as a Webcam with VB .NET But I want to change the interface of form then after I customize my new one with button, picturebox (with the right name), copy the code again except this paragraph #Region " Windows Form Designer generated code "
I have a project which still runs fine without issue however i dont seem to be able to access the design view of Form1. The icon in soultions explorer has also changed from a form to a sinple vb reference. Im unable to right click in solutions explorer and view designer as there is no option there.
