View 1 RepliesIn VB 2008, I have a Parent form with a combo box on it. There is a child form also with a combo box on it. I want to be able to change the values on the child form based on what the user selected from the main form. The user launches the child form from a toolbar on the Parent form. The following code is run:
[Code]...
What I want to do is if the Parent's combo box has "Red", "Blue", "Green" values and the user selects "Green", the child form's combo box(With the same values) will also change to "Green". (I do not need to change the Parent form if the child form changes.) I've tried changing the Child's combobox from the combobox's change event on the Parent form, and the code runs, but nothing changes on the child form.
In MDIParent, in my formload in MDIParent, one form is load. And i want the form when i click a button, there is another form will be loaded INSIDE the MDIParent?
View 4 RepliesWhy 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

I`m developing a desktop application using Visual Studio 2005 and a vb.net code.I`m using one MDIParent form 'frmMDI' and about 20 Child Forms. In the frmMDI there is a MainMenuStrip that contains 20 ToolStripMenuItems each one used to load a corresponding child form through this [code]So, that code is responsible to load a child form. Now what I`m facing after the loading of the child form is that the behavior of the controls of that child form is not so normal. you can`t set the cursor to the end of the text in a textbox.
View 17 RepliesHas anyone had any luck with having different window states with multiple open child forms?for example if you have a single child form opened and say it is maximized.then open a second child form as normal, the first form will then be set to normal.all the open child forms will mimic the newly opened forms state.and i believe they will mimic when making some changes to one forms state.the others will follow.i have not had luck keeping this from happening in most situations.

Anybody know a way to detect and set the form size in the child and MDIParent forms?
I'm having all kinds of problems from scroll bars popping up, to can't get the form to fill the parent. Pretty sure I have tried every possible combination in the forms properties 10 times.
I'm really getting tired of beating myself against this. Anybody seen a good tutorial on the finer points of MDIparent / MDI Child page size, etc.
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?
View 1 RepliesI 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

Looks like a dumb question, but I tried the following (where "Me" is a MDIParent form):

Dim frmreleasing As frmPostap
frmreleasing = New frmPostap(Me, release_record)
frmreleasing.MdiParent = Me.MdiParent

If this has been answered elsewhere can someone point me in the right direction. Instead of having visual studio's update screen i want to have my own screen pop up within my mdiparent form and have abit on the popup where i can display the changes that have been made (i can try and work this out with text files etc.)

View 1 RepliesI have a video control AxLiveLib.AxLiveX that displays video from a networked surveillance system. I'm trying to integrate this system into an MDI project, but when I set the form.mdiparent property on the form that has the video control, I no longer display video.I have a status bar at the bottom of the form that tells me connection status and current bitrate, so I can see that I am connected to the system, and if I comment out the 'FrmV.MdiParent = me' line on the parent form, I can see the video through the control.My question is what changes about the child form when you set it's MDIParent property? for example does the mdi parent take control over the forms refresh or draw functions?

[Code]...
I have a Form which has a variety of controls on it backed by an abundance of code. I am contemplating replacing some of the controls with third-party controls. What is the easiest way to do this? That is, in a simple example, I may want to just replace the Form itself (i.e. use third-party form and keep using Visual Studio controls). Is it possible to migrate all the existing controls over to the new form. Or do you have to create everything from scratch on the new form (i.e. create all the controls from scratch, name them the same, and use the old code. Note I am assuming the third party controls have all the same properties which may not be the case).

programmer and anything related with IT. i'm trying to create a program for my internet cafe wherein i would need 2 forms, 1 which will contain the transactions and 1 to log in/out customers. I was able to make this using excel but am currenty having a hard time now creating the program with VB2010, because syntax/formulas seemed different from that of excel2010... i have so many questions that i would like to ask, but i'l start with loading a form(for logging in/out) by clicking the Log-in button.
what i used before when i created a userform in excel is this:
Private sub LogBut_Click()
logForm.show

View 2 RepliesThis is what I'm trying to accomplish: I have a Point of Sale application that integrates with a credit card processesor. I wan't to remove any user interfacing logic in regards to the credit card processor in the point of sale and add it to a application that sits in the background or system tray. I want to be able to send a command to the background app to popup a form for user input.
For example: User in the Point of Sale clicks a button "Credit Card" at this point it will send a command to the background app say "ProcessCC" which will pass a transactionid and an amount , this will open a form for the user to enter in the credit card information and submit the payment to the credit card proccessor.
Reason: I need to get a padss certification and don't want to submit the point of sale to do it. Rather send the simple background app that will control any credit card processing functionality such as encryption , storing etc. I know it can be done using sockets but was hopping for an alternative solution.
I am looking for away to include a power point slide show inside a form in vb.net 2005. Office 2007 will be installe on all of the client machines which run the program.
