Unable To Write To MdiChild Forms?
Apr 20, 2012I 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.

Minimize MDIchild Windows To The StatusStrip?
Apr 15, 2009how 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.

VS 2008 : MdiChild Form In Tab Page?
Apr 7, 2011I 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.
Windows :: Maximize An MDIChild Of Another Application?
Sep 4, 2009I'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.

View 4 RepliesControls Increasing In Size When Form Is MDIChild
Jan 27, 2012I 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?

Form3= This is where I let the user input the necessary fields like Lastname, Firstname,Age,etc...

View 1 RepliesMDIParent Button Click To Display MDIChild Form?
Jun 9, 2011I 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?

View 2 RepliesForms :: What Is The Best Way To Update A RichTextBox
Oct 5, 2009Yesterday I was working with a RichTextBox and decided to add some formatting to my logging (I've never formatted text in one before!! O_O) ...not quite what I expected! Now, normally I work with plain unformatted text and I have an imposed limit on the number of characters I allow to be displayed in the GUI log. So I did my usual thing: After the length exceeds my cap I remove all the oldest lines from the log and set the most recent log info as the .Text property of the RTB... FAIL! All formatting was lost and things were ugly looking again. Sigh.

View 1 RepliesForms :: How To Update Progress Bar Within Class
Aug 12, 2010I am wondering how do I update a Progress Bar that resides in Form1 (for example) from a newly created class called from the Button in Form1. I have read several tutorial about backgroundworker. Most of the googled tutorials have their "long process code" in the do_work event. I have tried them and got it working from within the form itself.
However, there are 2 parts (long process) in which I wish to incorporate the updating of the progress bar; First one being a long sub routine that is in the main form (Form1). The second one is another long processing function that resides in a class. It is the second one that is giving the problem as I have no idea how to call the backgroundworker.reportProgress() to update the UI.
Here is the sample flowchart that I have created for the second long processing function:
I wish to insert a new instruction that says "Update the Progress bar that is in Form1" after the current instruction "Store the member into a collection".
Forms :: Update Datagridview From Three Comboboxes?
May 5, 2009I have three comboboxes in a form. The first is the parent of the second, which is the parent of the third. When they are all updated, a datagridview should be updated.
The problem is that the user can choose to change the value of either combobox, so I don't know which combobox's value is being changed. Therefore I now update the datagridview from the third combobox's selectedvaluechanged event. This unfortunately means that if the first combobox is changed, the second and third comboboxes selectedvalue events must trigger. As a consequence, when the first combobox is changed, the datagridview is being updated about six times (which doesn't work for me performancewise).
What I'd like to do is to call the updatedatagridview sub from either one of the three comboboxes, but only if the user has chosen to change that specific combobox's value (that is, get the form to only update the datagridview when the selectedvalues of all three comboboxes have been set).

Forms :: Using Update With A Table Adapter?
Feb 21, 2011I have a form that has a datagridview and a table adapter that displays data from a SQL database. What I'd like to do is that when edits are made to the data in the datagrid, I'd like to post all of the data back to the table. I know that you can do that with a dataset and a data adapter, but I don't know how to do that with a table adapter. Here is the code for my page:
