Check If Form Is Enabled On Resize Event?
Jun 21, 2010
In my application I have more then one form/dialogs, of course. My start up (main) form is called "StartForm" and when I want to access to some other dialogs, I open up dialog and I put StartForm on ".Enabled = False" so that user can't access to that form even if he click somewhere on it (StartForm is maximized to full screen and dialogs are small so StartForm can be seen in background when you open dialog). Ok, this works fine until I click on my application "link" in task bar...then, only my StartForm is visible and it's ".Enabled = False" so I can't do anything...I must kill process in task manager. Same thing happens when I open some other application and then come back to my application.

Back in the VB6 days, I could count on frmWhatever_Resize() to be fired when a form is loaded. That doesn't still seem to be the case. Since my resize event is filled with all the code I want that adjusts the size and placement of things, I decided to just call it from the end of the form's load event. That has no affect. I'm guessing that the form isn't actually shown until form_load is finished?
is there some other event that is fired when a form is shown, so I can call my resize code there?

I created so many listviews in my project, that im too lazy to add to each listview a resize event with percentages. Is there any other trick, who just scales the columns so as they are?

I'm starting work updating an UI for one of my company's applications and I'm running into a sticky issue. The parent control contains several panels, each of which can be turned on or off depending on user input.
The final panel in the user control contains another user control which gets resizes according to a toggle switch. Essentially, it "opens" up more information.
While the child control (ChildControl) is docked to Fill inside the parent control (ParentControl), when I add height to ChildControl I can't get ParentControl's height to get updated as well. Currently I'm handling the ChildControl.Layout event in ParentControl but I can't seem to reach that code. To resize ChildControl, I'm calling Me.Height += 200 in ChildControl.vb.

Is there any way to check from .NET if windows update is enabled?
I want to prompt the users every time they log into my app that their computer might be at risk and give them a link to windows update website (or windows update application from control panel).
Preferably it should work on XP, Vista and Windows 7. Maybe there is a registry key or even better an API?

I want to do a For Each loop where i can check whether each button is enabled or disabled. If the button is enabled then i have to obtain the values in the tags for each button. I have 26 buttons each containing different values (cash prizes).*IMPORTANT: this code needs to go under the button so every sixth time its pressed it checks the buttons.
Pseudo-Code:
btncase1.tag = 5
Begin while statement to go through each button
Check each button to see if it is enabled

Following on from my post yesterday (how to anchor buttons/controls to various sides of the current form when the form is resized) I have run into another problem. I am setting the width of my datagrid to be 80% of the form width on a 'form resize' event with 10% of the width at either side so it remains centred in whatever size window is available. This works fine. (mydatagrid.width = me.width/5*4)
I then decided to dynamically set the width of the 2 columns in the datagrid each to 50% of the width of the datagrid. Again, this sub is called in the 'form resize' event. This fails because the datagrid hasn't loaded the data from my sql database when the first 'resize' event is triggered. I did a bit of testing (by placing a simple msgbox statement into the resize event and the load event) and it seems the 'resize' event is triggered three times before the form's load event.
how do I stop the resize event triggering when the form loads (or at least make the load event trigger first).

I have a VB. Net App where I want the user to open a modeless form which contains reference information about items in a select box. If the user double clicks the item selected in the list box a modal form is opened to edit the item.I want the previously opened reference form to remain active/enabled, that is, I want the user to be able to click on it, move it, etc.I was able to get the form to at least show up on the task bar by setting it's "ShowInTaskBar" property to true, however, when it comes to the front the user can still not move it to the side to view all of the Edit Forms information.

I have set up a Textbox Resize event, but when I execute the form, it doesn't allow me to change the textbox size. I'm not sure what code to show; this is a VB.Net book exercise that I'm running in VB 2005. [code] I have tried setting the Border to something beside 'Fixed'. All resize references I have found refer to Forms or tables. Is there a property that allows users to resize a textbox?

I've tired to use KeyPress event while in focus of my program's window in VB.Net, but it doesn't work.
For example I wanted to press the number "2" anywhere while in focus of the application and as effect the pixels of the window will change from 200,200 to 600,600 (hortizontal and vertical)
Private Sub Form1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles MyBase.KeyPress

using VS 2010, writting small app which utilises wmp.dll (ver: 12.0.7601.17514 (size: 13.9 MB (14,633,472 bytes)).All works fine except on the openstatechange event the player object resizes every time to approx 250x250. Its driving me MAD!. I have even entered overiding height and width values which it rudely ignores...its a bad bad COM object.I have definately captured the event point where it resizes itself to the exit of the openstatechange event.

So I am playing around with the resize event. My form is 500 wide, my button.left is at 100. If I use:
Dim int As Double
int = button1.Left / Me.Width ' this = 0.2
'resize event
'Button1.Left = (int * Me.Width)
TextBox1.Text = (int * Me.Width).ToString
The number in the texbox is correct - proportion wise, but it won't set the button1.Left to this number. I'm sure this is because int is a Double where .Left is an integer?

I am making a configuration screen so that an administrator can easily determine what controls on a form are enabled according to a combo selection.
I have created a table (SQL2008 DB) to store the settings and need ideas how I can best implement.
The session form will start up normal with only a few controls enabled to start, but then when the user selects a "session type" from a drop down combo then the form will be configured for that type. Because there may be several different combinations, and I do want to offer the user the ability to add and configure more types as needed I feel like this may be the best method instead of hard coding.
Table Structure
SessionType varchar(25) not null PK
ControlSwitch varchar(50) Not Null
(Edit: I may add an additional DB field so that I can specify the default value of a control also)
Now what I thought I would do on the config form is have a series of combo boxes and the label represent each control with a value of True or False, then when saved it builds a string like example 1,1,0,1,0,1,1,1 or True, True, False etc.
The string would represent
ctrl1=on, ctrl2=on,ctrl3=off,ctrl4=on,ctrl5=off,ctrl6=on,ctrl7=on,ctrl8=on and so on.

What is the best way to resize & move a form using just VB commands? I have a form that I need to set the Height and Top props, problem is that takes two calls and there is a noticable flicker. I tried using SuspendLayout/ResumeLayout, DoubleBuffered, swaping the top and height calls around, etc, but nothing seems to help. The test forms only have one small listview and one or two buttons.

As i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.

Alright, I need some way to generate a printable report from a text file. I'm thinking that the easiest way to do this is to create a form which will layout the information and then reading from the text file into the controls of the form. Then taking a screen shot of the form itself, and storing it into a bitmap and printing it.[code]...
