I have a program developed in VB.NET (2008) which consists of a MDI form and several child forms. It worked like a normal mdi application whereby mdi form acted like a container for child forms and things worked out okay. Code like Me.Mdichildren or Me.ActiveMdiChild etc could be used to get list of child forms and perform other actions.Now what happened is I needed to implement a tabbed system. There will be multiple tabs and forms would be in those tabs. So I added a Tab control in mdi form and now new forms are added to selected tab page. This way muliple tab pages can host forms and there is no need to see all childforms at once.
But a problem has come up. I do say ChildForm.MdiParent = Me (as before) but then I say TabPage1.Controls.Add(ChildForm).Doing so functions like getting list of mdi children or me.activemdichild or auto arrange options like Cascade,Tile Horizontal, Vertical etc are not working. This will be a major problem for me.
I hava a MDI app. i have a mdiChlid(say A) and others n instances of another mdichild. i wanto to this others n instances can handle an event generate in the A mdi chlid. How ca i do this??
Why is my MDIChild form not being displayed in my MDIParent form? I want to click a button on form frmStudyResultsFilter which will then display an MDIContainer form frmCalculatedResults (maximized). When frmCalculatedResults is shown I want a small dialog modal form to be in the center of frmCalculatedResults. For some reason frmCalculatedResults will not show on top. Plus I get this error"Form that is not a top-level form cannot be displayed as a modal dialog box. Remove the form from any parent form before calling ShowDialog." Here is my code:
Public Class frmStudyResultsFilter Private Sub btnCalculated_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculated.Click Dim frm As New frmCalculatedResults
how can I check(with code) if an mdichild form is already opened or not. I have some mdichildforms that may open together. If an mdichild form is opened I want to dislpay the already opened form and not a new one.
I placed a button on my form that measured 59mm in width (approx 2.25 inches for any Americans).When you run the project as you'd expect it still measures 59mm.However when I set the form as a child to my MDIParent and run the project the button now measures 67mm (well over 2.5 inches) an increase of 13.5%.Is this a bug or do I need to just change some setting somewhere?
I would like to display the autoscroll bar on MDIParent form when user moves MDIChild form. I set the autoscroll to false on the MDIParent form, but it does not display the scroll bar. What should i do?
My application having one mdiform in that form six child forms are there.Switching of opening one childform into anather form speed is very slow after clicking of any button in the mdiform.
I have developed a small application. It has a MDIParent form on which the other childforms are displayed. I have a Panel on the MDIParent on which there are buttons to call up the MDIChild forms. Now my issue is, when anyone of the buttons on the MDIParents form Panel are clicked, it should check if another Childform is display, if it is then it (the active childform is closed) and the new form will be displayed. This part is working fine from the code below. However, when there are no active MDIChild form on the MDIParent form and if the button is clicked, the 'Else' part of my code below is executed. This generates the error as 'Object reference not set to an instance of an object'. So what is wrong with my code below?
Private Sub btnExecutive_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecutive.Click Dim MDIChildForm As New frmExecutiveInfo
I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.
I have a SCADA program I'm working on, I need to add sum sort of paging when the user hits the page up/down button. I have about 100 station to show. I can fit 28 stations on one screen at 1280 X 1024.
I need to press a button on a web page that is not located within a form, so how do I press a button according to its html element ID?Here is the HTML for the button by the way.:
<input id="i0011" class="css0088" type="submit" value=" Sign in " name="SI"/>
What I'd like to do is in my application move a control like a groupbox or frame with content on it from e.g the main form to a tabpage on that same main form using code.
I can change the position of the control using it's location, but I haven't got a clue on how to move it from the main form to a tabpage, or from 1 tabpage to another.
-Is this at all possible and if so, how can it be achieved?
I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.
I have need for a customised form as the main page of my app, what I'm looking for is to create an amoebic shaped form, something like this. I realize that my 'window' will by nature need to be rectangular and that i will need it to have no titlebar and transparent edges, also i will need to have 'regions' on this form that will allow the form to be closed and turned into a standard rectangular form. I have no idea where to begin with doing this but I hope and presume it is possible with vb.net. The image I have used is for illustrative purposes only, i don't plan to do exactly this (my app is a database not a media player for one thing) If having it is a breach of copyright in this context I will remove it.
I am making a program that will fill in some info on a form. The information that needs to be filled is:
[Code]...
The thing is i need the program to click on a button on a website then open a new tab with the page it just clicked on, fill in email and click submit, then fill in the info that is above before pausing. I would also like the info above to be randomized each time the new page loads so it is not the same. I have already looked on this site and cant find what I am looking for.
I am having problem with my windows based application in VS 2008. I have a page from where I copy the component and use the same on another page for saving my designing time.It works fine and run without error.But when I restart the solution then the 2nd page where I had pasted the component is not displayed in the form designer. I get the following on the screen
I have made new MDIChild and with textboxes on the form. When the form loads...it will open data saved from a text file to the textboxes. However the data does not load from the text files. When i take out the code, it works fine...but it needs to be a mdi child...the code i'm using is
Dim NewMDIChild As New ViewCustomer() NewMDIChild.MdiParent = Main NewMDIChild.Show()
the form that I need to load the info is "ViewCustomer" and the mdi parent is "Main"
I have an App with 4 childMDI forms in VB 2008. What I need to do is update 1 of the childMDI forms when I close another childMDI form. How do I do this in a best practice way?
I have a MDIParent form that has a bunch of child forms. When I open a child form, I can actually move the form outside the bounds of the Parent. How can I prevent this? I've set each of the Child Forms "IsMdiContainer" property to "False". What am I missing?
how to minimize MDIchild windows to the StatusStrip...or is there another toolbar object in VB.NET (2008)? I have a menu layered over my MDI Parent window (which is always maximized) and if I minimize another child window, i can't see it anywhere (unless I minimize the menu too, but I took that ability away from the user)... I think I know how to do this through the menustrip at the top of the window (click on open windows....like in excel or word), but I'd like to see the windows minimized in a toolstrip of the MDI parent.
I have a main form with a number (in this case 9) mdichild forms. Some are visible, some not, but they are all very basic. When I write to a textbox in any child form during Main_Load it updates, when I write to a textbox in any child form inside its own _Load it updates. If I write to one from awhere else in code, including a sub in the form's own code, it fails to update.
All the child forms are identical but are distinctly separate forms created before compilation rather then NEW versions of a single form to avoid threading problems.Curiously this code worked once only. No edits were made and when re-ran failed after stopping it if found all the controls in some of the forms were invisibe in developer mode, restarted VS but still not there. Run app and at runtime there they were!!! Also all locked textboxes still accepting input.
I'm making an appication that needs to maximize the window of another application. In Spy++, the way it works is -> "Working Model - Untitled1" -> "MDICloient" -> "Untitled1"This is what the tree view looks like.I need to maximize Untitled1, but I'm not sure how. I tried findwindow "Working Model - Untitled1" and then used get and setwindowplacment for it, and it worked. Then I used findwindowex on "Untitled1" but it did not maximize. What am I doing wrong here? I'm sure mdi windows can be maximized; the "Untitled1" window itself has the 3 buttons (- + X) on the caption bar.
I am using a tab control on my mdi parent forms. when i open a child window i hide the tab control. but i want the tabcontrol to show itself on child close event. but i cant figure out the code.
