I am in the process of upgrading a VB6 Project to Vb.net. My problem is that when I open a child form in my project from within the Parent form a new instance of the Parent form is created. The code is fairly simple:
frmnewContract.MdiParent = Me
frmnewContract.Show()
I am developing an application with VB.net and SQL Express. In my application I have many forms as : some of my forms are :
Mainform
selectmonth_form
Form_report[code]....
Forms load normally and also show all data in form_report. With this code these forms open as new windows, but I want to open windows as child window.
I have a Visual Basic form with a public sub procedure called xecute_Public_User_Defined_Sub_Procedure.I tried to call the sub procedure from the "ParentForm" below but could not.
Dim ParentForm As Form = CurrentTextBox.Parent
If ParentForm IsNot Nothing Then
ParentForm.Execute_Public_User_Defined_Sub_Procedure()
[code].....
I have a form that creates an instance of a New Class. The code is simple so there is no issues with the programming.
I can step through the code on the Main Form without issues. Stepping Into moves from 1 line to the next.
I can't seem to debug the code within the class though. I set breakpoints but "stepping into" doesn't work. The code gets executed, but it doesn't step through each instruction.
I've tried changing many of the options within Tools > Debug with no luck.
I've tried deleting files from bindebug and obdebug.
Not being able to debug my programs.
The Parent has a Tool Strip and on the tool strip is a button that when clicked loads the child, this works fine.But when I set the child form to maximize its title-bar jumps over the Parent tool strip. Pushing it down a bit. I do what this. I would like the child to be completely contained within the Parent including the Parent forms tool strip.

View 37 RepliesI need to create a new instance of a class that needs a member of the calling class. But i can't pass a reference to the calling class through the constructor.The solution i am looking for is something like this:

I want this to work without having to manually pass any references or variables from the calling class to the new instance of ChildClass.

The problem is that this code is Opening a new second instance of the first form (Form1), when I see in debug mode and move my cursor over the frmPers variable, It's value is Nothing, altough I am seen it at the screen ¿Why is this? I am loosing my hair after three days trying several forms to do it without any results.
I have an application that has a tabcontrol to handle multiple documents, just like Notepad++. And I also have file association working correctly with it.All I want to do is to make it open the double-clicked file onto a new "codetab" instead of creating a new instance of the program just to open a file.
View 2 RepliesHi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

View 1 Repliesi have a MDI application with parent and childforms.
i have a global timer in a module that makes a com search and writes the result to a parentform status strip label.
the problem is that the label do not change.
i have tried the following:
1) on timer.elapsed
parentForm.statusstriplabel.text =...
2) to create a delegate and invoke a parent form function
3) to create and raise an event
although all 3 seened to run the label didn't changed.
the timer was created in a different module than the parentform class for many reasons.
one of them is because i want to access the timer.start , timer.stop from all the childforms
when i tried a local timer to paretform worked perfect but i couidnt start and stop it from the childs

View 24 RepliesFirstly though, I'll have to mention that I'm a relative newcomer to vb.net and don't really know that much about advanced functions.I have my main form which dynamically generates 15 buttons.
Each of these buttons will need to open another form, depending on which form has been assigned to that button in a config file (the config file isn't yet done, as I want to get it working simply by hardcoding the name of the forms for the time being)
The way I have it in my head is that I would assign the form name that needs to be open to the name of the button, if that makes sense....However, I have absolutely no clue how to do it, I've tried a couple of things but to no avail.
Here's my code, and I have no problem changing any part of it if it will help things along, this is just the only way I know how to create dynamic buttons.[CODE...]

View 5 RepliesI want to open a VB.net form using a ThreadPool with a maximum of 10 threads. I need to do this because, the form should open based on a live event and i need atmost 10 forms on the desktop at a time. If i open the form on every live event without using a ThreadPool, the desktop will be floaded with many forms. I am using QueueUserWorkItem method of threadpool to queue a method which opens the form. In this queued method, there is form1.show() statement called. But after displaying the form, this method finishes execution and again we have 10 threads available in the system. I somehow want to either keep this method running so that 1 thread is occupied or i want to keep the thread alive till the form1 is closed by the user. I want the 11th form to appear on the desktop, only when any of the existing forms out of the 10 (already on desktop) is closed.

View 15 RepliesOver the past months I have been working on small windows forms applications and learning vb as i go along. The aim was to pull these altogether into one big application.
I am now at the stage of pulling these together I have created a new project (called MainMenu) and designed all the buttons and interface. I have added my other projects (SISApp, CURApp) to this project. File > Add > Existing Project. I can see these projects in the solution explorer.
Now my problem. How can show Form2 in the SISApp project when I click ButtonX in the MainMenu project.
I dont just want to show Form2, i want all the functionality and the database connection in form2 to also work etc.
I might be going about this the wrong way, but I'm trying to create a form that will include a single button, for instance "Enter". When "Enter" is clicked, I want the form to then display the contents of form 2, which might include more buttons and/or a textbox, etc. I want to do all this without ever opening or closing a form.

As you can see, I need loopong through all the open child forms.
I have a form which gets populated by 15 buttons dynamically at runtime (these need to be dynamic as there will be a user config file at some point)What I need these buttons to do is to open a specific form when clicked. Which form that opens will be dealt with in the config file.

Private Sub frm_MainScreen_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim ImageDir As String

View 1 RepliesI am making a webbrowser,how to prevent my browser from opening new IE windows. Because what happens is, there are some links that will open new windows and therefore IE comes in place because it is set as default windows browser which I really don't want because my browser looks really bad if it opens links in another webbrowser.I want it to be just a basic browser, it has only one window, and it should navigate within that window. This is because the browser is integrated in a bigger application only for some website applications that are related to this main application.I am using VB.net 2008 Express Edition?
