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.

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 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

I'd like to design a Winform with expanding controls if that 's overly complicated. The idea is that I would have rows of information, each with an "Expand" button. On pressing the button, the rows underneath the selected row would move down and the controls that are associated with the selected row (some textboxes/ dropdowns etc) would appear. Vice versa when you click the "Hide" button.
View 2 RepliesI 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 solution with about 5 projects, the main (startup) project is a windows forms project while the others are control libraries that contain some custom controls. The main winforms project however also contains some custom controls.
Recently, the controls in the main winforms project have stopped appearing in my toolbox. The controls from the other control library projects appear just fine, but none of the controls in my main project will show...
Some of the projects are VB, some are C#.
I have tried everything I know to fix it:Delete bin/debug folders and restart
Build, build, build, build, and build Target the same .NET Framework version and CPU platform in all projects Build again Nothing works...
All projects target .NET Framework 4.0 and compile for the x86 platform (since I am using Access db). All projects build successfully, no errors. I can run the solution just fine. I can even declare and add the controls in code and they work just fine. They just don't show up in the toolbox so I can't drag them to my form and I have to dig into the designer code everytime, which is really annoying!
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 tried this to hide:
btnHide
Dim txt As Object
Dim tabp As TabPage
For Each tabp In TabControl1.TabPages

I've removed a few controls from my form, but they're still in the properties. I've looked in the Document Outline, but nothing. How can I remove them (save)?
View 6 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 have a bunch of controls on my form and am wondering if I can hide some so it doesn't look so cluttered.I only wnt to hide them on the designer though and not at runtime. Any way to do this?
View 7 RepliesI'm having a weird bug with a TabControl that I've never seen before. Here's what I got:
A TabControl with 3 tabs. The first 2 tabs have an inherited DGV on them, and the third page is like a options page. The 3rd tab has a bunch of labels, comboboxes, checkboxes etc...
Whenever I play/start debuggings/run the app the controls of the 3rd page turn "invisible" on the design view. They are still shown in the app. Here are two pictures showing what I mean:
This is what the designer looks like BEFORE I run it: This is what the designer looks like AFTER I run it (Running app on the right): I've tried building/rebuilding/cleaning and nothing. If I close the solution and VS and reopen it, it will show but that's a pain to deal with.
Showing and Hiding Forms from a Console Application causes "Cross-thread operation not valid."
View 1 RepliesAssume you have controls A, B, C, D and E all with a Visibility property. You also have states 1,2,3,4,5 and 6 in which various combinations of your controls would be displayed. Currently this is being handled by switch statements for each state: i.e.
Select Case PageState
case "1"
a.visible = false
b.visible = true
[code]....
As you can imagine, this becomes a pain as every state needs a show/hide statement for each control. How can I refactor this so that adding controls and/or states becomes trivial?My first instinct is to extend the control and add a collection of states that it should display for but this sounds like overkill.
Edit:I was deliberately vague in my question in case this has other implications. In my current instance the "controls" in question are ASP Panels. Does that change anything?
Yesterday I installed vs2008, installed SP1 all seems well.I have converted a project (from VS2005), it works fine but....When I try and modify any of the forms none of the controls aer displayed on the form.Additionally I have noticed that each form has a formname.designer.vb file, the top few lines of the code in the designer.vb files are;
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class frmFullMarketView
Inherits System.Windows.Forms.Form
[Code]....
Then my controls are listed. Do I have to copy the code held in the seperate designer.vb file back to the 'formname.vb' file for all my forms?If so, why does VS2008 create all this extra work when converting forms from vs2005?

View 7 RepliesI need transparent panels. I simply set that background color of controls to Transparent - this does not solve the problem, as the transparency simply shows the background color of the form, but does NOT show any controls placed on the form, which is the crux of my problem.Why? Because I'm trying to use this skinning example, which does the skin by creating a user control, and make the panels show the skin's background:[URL] It seems I'm going to have to override the panel and paint it's background manually, but I don't understand how it all works; I've created a new class and overridden the panel, but the painting stuff is way above my head.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Panel1.BackColor = Color.FromArgb(0, 0, 0, 0)

It seems like such a simple thing to me, but it seems like the usual, me.hide() isn't working in this case. I have 2 forms that tie together, the login form, and then the main for being form1. The login form has an autologin feature, which works out fine, but with it enabled, the login form doesn't automatically hide like it should.

I have created a series of custom user controls for a wizard interface that I am making. Each user control represents one step in the wizard and really shouldn't be used outside of the wizard. The thing that is bugging me is that each wizard step user control shows up in the toolbox of components to insert into a form.
Is it possible to hide a user control from the toolbox? Better yet is it possible to hide a user control from other classes not in the same namespace of an assembly? Is this a good approach or should I think of a different approach?
I've created a program with a login form. Once you log in, the login form should close and the next form should display... my problem is...
If I use Me.Close()... than both forms close and the application terminates.
If I use Me.Hide()... than the application never unloads from memory and run indefinitely.
So what do I do? Neither of these work how I need them to.
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.
