I was just googleing this, and i came across this
Dim p As New System.Diagnostics.Process
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
p.StartInfo.CreateNoWindow = True
p.StartInfo.UseShellExecute = True
p.StartInfo.FileName = "cmd.exe"
p.Start()
Does that mean that i could show it again? if so, is there a code that can do this?Also, if i wanted to get the window that the user is currently in, how would i be able to hide that?
When my login screen loads, if the user has not created an account the form will close and a form to create an account will appear. However when I code this both forms stay visible, instead of just the one. Where am I going wrong?[code...]
View 6 RepliesI've just upgraded from Visual Basic 6 to Visual Basic 2008 Express Edition.
1. Show anothor form (ie. Form2)
2. Close Form1.
At present when I use the me.form1 , but both Form1 and Form2 both closes.I would like to press a button or on a timer, to show Form2, while closing Form1.
I have a vb.net application that, when a short cut is pressed, a window pops up. I also would like to make it completely invisible, unless the short cut is pressed. In the default class that houses my code for noticing the short cut and coordinating the events of the short cut, I have placed the following code:
Me.ShowInTaskbar = False
I have isolated this code as the issue. The issue is that my application does not work when it is not shown in the taskbar. This is only the default form - for the pop up window I have a separate class. How can I create a workaround for hiding the window in the taskbar and hiding it in general?
Btw, this is my hotkey code:
Public Const MOD_ALT As Integer = &H1
Public Const WM_HOTKEY As Integer = &H312
Public Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer, ByVal fsModifiers As Integer, ByVal vk As Integer) As Integer

I am trying to show or hide tabpages as per user choice. If user selects gender male then form for male in a tabpage "male" should be displayed and if user selects female then similar next form should be displayed in next tab "female"I tried using
tabControl1.TabPages.Remove(...)
and
tabControl1.TabPages.Add(...)
It adds and removes the tabpages but doing so will loose my controls on tabpages too... i can't see them back. what's the problem here?
The idea is simple, if I have a string value "ABCD" then with a ButtonClick event it should randomly reveal a char while others are hidden. i.e, "B*" another click would "AB**" and so on. So far, my I have been stuck in a for loop.

I'm trying to search through all tabs to find a specific text. if the text is found, the tab will be hidden, or shown.

I have a form that searches a db. Some searches will always result in one row of data, others might return multiple rows. I want to have the data from a single row shown in text boxes and the multiple rows show in a datagridview is it possible to hide/show those depending on the amount of rows.
View 6 RepliesI am using a MDI parent to house each of the forms in my application. I have a main form and 2 sub forms. The sub forms are opened using the code below. Also, when I am finished entering info into these forms, i am hiding them so that I can reopen them with the same info still entered.
The problem is that when i show the form again, it is blank. Why would this be the case? I am never closing or disposing the form, so shouldn't it just unhide easily?Showing the sub-form(savingsfrm1) and and hiding the main form(riskfrm1)Public savingsfrm1 As Savings

basically i have a form with loads of controls. So many infact it stretches the whole hieght of my screen.I only need half these showing since the rest are just a sort of 'log'I have seen ti done loads, that only the controls i want to show at start up are displayed then when some one hits a little button in the bottem it expands the rest leaving them showing to.
View 9 RepliesI have a form e.g. Form1 , which displays a datagridview.
1) On form load, the datagridview doesn't have any data
2) The user clicks on a button called filter, this opens a form where the user can specify parameters to filter the data by
3) This form calls a setData() in Form1, which fills the dataset with the data
This works fine. If I click on a button called controlPanel it launches another form and hides this. E.g.
dim cp as new ControlPanel()
this.hide()
cp.show()
On the controlpanel I have a button that links to form1. If I click on it. E.g.
dim frm as new Form1()
this.hide()
frm.show()
It redisplays Form1 but without any data in the datagridview.
I think the problem is that since I am creating a new instance for Form1 it comes up with the blank Form1. Is there a way to redisplay Form1 so that it retains the data that was displayed last, without having to retrieve the data from the database.
I've embedded a form into another form by changing the Top Level property. My problem is that the new implementation does not allow me to edit the DataGridView at runtime. Here's the code I'm using from my main form:
Dim f As New form2()
f.TopLevel = False
Me.Controls.Add(f)
f.Show()
f.showRows()
f.showDbvHeader()
When I call the two methods on the onload event in form2 they run OK for the remainder of the event but as soon as it ends, the DGV reverts back to default.
I have a form which has a picturebox and after clicking on a button another form will appear with a picture box containing the exact same picture. I use this line of code:Image1.Image = vImage.Image..The thing is after I do this i need to hide the form and show it again to be able to see the changes.[code]
View 1 RepliesIt is times like these that I miss the old VB6 language I wish I could hide the current forn and show another form which - this is the important thing - to be on the same level that the previous form was . You see , I used to use this code :
Me.Hide Form2.Show However , sometimes in VB .NET this does not work the way I want it to . You see , the current form does get hidden and Form2 is shown indeed ; however , Form2 is shown somewhere in the background . If there are other programs opened at that time , then Form2 is shown behind all those programs , that's what I mean by saying I want it to be shown in the same level as the previous form was the only way out , I found , was to reverse the code :
Form2.Show Me.Hide In this way Form2 is successfully shown right where the previous form was shown (above the other programs) but in some cases this also is not pleasant because it might take some time for Form2 to load while at the same time the previous form is still visible on the screen and therefore for a slight time both forms are shown one over the other , which is surely not nice . That's why I still want to first hide the first form and later show Form2 .
I'm having an issue with my app where IE will get brought to the front of the screen when I am switching between forms. Basically I have a form with the man menu which consist of a few command buttons that will start up another form once a user clicks on the button. I do not want the users loading up multiple forms in my application, so once they load one form I end up hiding the main form. So my code looks as shown below when a button is clicked.

I'm making a webbrowser and coding the ctrl+f function has proven to be too complicated. I therefore decided to link buttons with the ctrl+f window that already exists in IE. What i want to do now is hide the ctrl+f window that pops up. When I hide active window at the moment it hides the webbrowser and not the ctrl+f window that pops up.

I have created an application domain, using which i am executing an .exe file.So the command window does open which has the title as file name. I want to hide the command window.
Dim newAppDomain As AppDomain = AppDomain.CreateDomain("", AppDomain.CurrentDomain.Evidence, AppDomain.CurrentDomain.SetupInformation)
newAppDomain.ExecuteAssembly(IO.Path.Combine(Offic eAddInConfig.Instance.BinPath & "Core", "file1.exe"))
Here a command prompt will be opened which need to hide.
So i want to start an application with my vb.net app and it should start as a hidden process, meaning no window and nothing in the task bar, only in the task manager ofcourse.
This is what i do
Dim fov As New Process
If CheckBox2.Checked = True Then
RichTextBox1.Text = RichTextBox1.Text & vbCrLf & "* - Launching"
fov.StartInfo.FileName = ("test.exe")
[Code]...
This does not work.. I have also tried the "fov.StartInfo.CreateNoWindow = True" command which does not work either. I can live with a solution that would start the window minimized instead of totally hidden.

View 1 RepliesI am looking to call plink from a vb.net application in the background (without showing the black plink cmd screen) is it possible?
View 1 RepliesI have a form (f1) and a popup form(p1). On f1, when I click on a button, I call p1 like such:
Dim spp As New p1
spp.ShowDialog()
and in p1, I have a progress indicator that shows a long running process. The problem is that p1 doesn't show. I tried invalidate, update, refresh, doevents, etc. (both in f1 as well as p1). Nothing. p1 just doesn't show.
I have 2 desktop programms..I will call them P1 and P2.So, P1 launches P2 as a process. However, at some point I want to be able to show a window in P2. My problem was that this window, when called, was showing correctly placed, in the middle of the screen, but in the back of P1.So, in order to show it as the top most window, above all others applications running on my computer, I used the windows API:
Const HWND_TOPMOST = -1
Const HWND_NOTOPMOST = -2
Const SWP_NOSIZE = &H1[code]...
Now the window shows on top of all other, but it is placed in the top left corner of the screen, resized to much small dimentions, that I cannot even see the controls on it.

View 1 RepliesI am trying to show a message box when an error occurs in a modal dialog window but for some reason the message box is never shown although I know the MessageBox.Show method is being hit. The try catch block is inside of an event handler for a windows form that is being shown as a modal dialog. I know that the event is being fired and that the error is being caught but the message box never opens. I've replaced the MessageBox.Show with another form show and it works fine but I'd rather use MessageBox instead of creating my own error form. I just can't seem to make MessageBox work. Is this a limitation of MessageBox? Here is a simplified version of what I am doing:

I made the awful mistake of using a module instead of a class. Now, I have a control, (who inherit from a web browser), hidden under a modal form. And I need to show his content (and being it clickable) to the user, but it is hidden, and I don't want to mess with the Showmodal of the hinder form. Until I modify my code, so I can do multiple instances of my browser, I need to show that control to the user on a third form. I think that I can temporary change the .parent property of the browser, so a third modal form shows it.
But I fear that I possibly made the browser control hard coded as working in the bottom hidden form, so If I change his parent, I may broke some logic. Is there a way to show the control on a third form, without changing his parent? (and still have it clickable). I know I are asking for trouble. It is only a short term solution until I move all my module into an instantiate able class. (And I remember had being advised to work ever with classes instead of modules. Now I learn the lesson the hard way).
I have in a console application. I need the program to show a OpenFileDialog window when certain text is entered, such as "file". I've tried doing this and I cannot get it to work.
