I'm trying to load an exe made in another language for a project I'm doing into my VB.net MDI parent form, but I can't seem to find anything. I've tried using the SetParent API and the like to try and achieve it, but nothing seems to work. SetParent freezes the parent form completely and makes it non-responsive.
View 2 RepliesI have 1 form as parent MDI (frmParent.vb) and have 2 child form (frmChild01.vb & frmChild02.vb).the code for parent form as per below.
Public Class frmParent
Private Sub OpenChild01ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenChild01ToolStripMenuItem.Click
Dim child01 As frmChild01
[code]....
My problem is how can I set label1.text in frmChild02.vb when user click button1 in frmChild01.vb
Im working with MDI parent/child objects. when closing the child objects i need the child to check to see if it is the last child object before closing. i couldn't find anything on google, maybe im searching for the wrong thing.

I have a bunch of XML's that need to be put into an SQL database. One XML represents all orders for a certain department of a store. The problem (for me) is that in one XML there can be (and are) multiple orders (called distributions in my case.) The XML looks as follows (truncated):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<order><process_id>322867</process_id>
<key1>RET</key1>
<key2>40_134985</key2>
[code]....
So in this example I have two 'distributions'. Now I can get all data out of the XML fine, which I do like this:
get xml data
awsFeed = XDocument.Load(fileName)
Dim orders = From order In awsFeed...<order> _
[code]....
However, in this case my SQL input would have to result in 2 entries, because there are 2 orders. Both entries would have the same data, except for different entries. I know how to post to SQL, that's not the problem. My real problem is, how do I 'loop' it through the XML. I think i'm looking for something like:For each 'distribution' in orders -> put into array.Or something like that. After that I could query the array and put it in the database.
In the project I'm working on, I was editing a class and when I got done, I clicked save all. I moved on to my main form's designer. When it came up, the custom tab control I have on the form was blank. There used to be a ton of controls in it, so I am extremely confused about where everything went.I checked the properties window and it thinks everything is still there:ut when I check the Document Outline window, everything is gone. The tab control is still there, "AVERT Wizard", but all of it's child controls and tab pages are gone.

I have an MDI parent form and multiple child forms. Child forms are borderless and set to start in the maximized position because I want the forms to completely fill/resize within the parent form and only display the selected form, one form at a time.
Problem I have is whenever I load a form it puts another bar at the top of the screen and another control box. Is there any way to get the child forms to load in maximized state without this bar? I tried .controlbox = false and it gets rid of the control box but the bar is still there.
I have a MDI project that has a parent and several children forms. In some of the children forms I would like to make one of the forms to be a parent form with children. On this child form I wanted to make a tabbed MDI, which I can do, but I have found out that I can't make a child form a parent, from what I have found.
Is there any way to get around this? (As in nested MDI forms.)
I am trying to create a simple parent-child form in VB2010. I use a datagridview for each table/datasource and each is bound to the parent/child table and each table grid fills correctly. What I want is the parent-child relation to enforce filling the child table with only rows that fulfill the current row on the parent. I have created a DataRelation in the form load, but it will not permit a relation between tables in 2 different datasets. If I attempt to place both tables in a single dataset and define the PK-FK relation in the SQL Server I cannot create 2 separate datagrids from the same dataset.

View 12 RepliesI've created a form that has a timer control. When this form loads it counts down before running a procedure. Simple.
Now I want to subclass this form in a new VB.NET project to so that another form inherits this form (an it's timer functionality) and runs a different procedure on this new form.My problem is that when I create the form in my new project the timer from the parent form seems to be running and when it's time is up it runs and code and crashes the VS environment.
I've searched high and low but have only found references to making sure the timer is disabled at design time. I've done this on the parent form but in this parent form's Load event the timer is enabled.... the purpose of the form. So when the child form loads it is enabling the timer. How can I work around this? Can I enable the timer from the child form? Timer is not visible when the child form loads so how do I manipulate it?

My program handles XML files that have certain elements within a root-child node that are identical expect for their inner text value. So while populating my combo box with all of a root-child's child element's names I get like five identical items listed. Which brought about the problem of selecting say the third item and getting the value of the first displayed. So I came up with a loop function that determines if the selected combo box item is preceded by one of the same name, if it is, then it adds +1 to a counter variable and keeps checking farther and farther up the list. Once it loops to an item that doesn't have the same name it exits and it reads the Xth (X = counter mentioned earlier) element's inner text from the file. This works great for elements 1, 3, 4, and 5. But not for 2. A while back when I was focused on this problem I discovered the root of the problem but I was unable to circumvent it. I'll put the loop below so you can see the problem in action instead of trying to follow my verbose explanation:

I'm from denmark and hope I can explain my question for you. This is just a example: I have a panel, let's say panel1 and another panel on that panel (panel2) and so on until for example panel5 - on panel5 I have a button (button1). Now I would like to change button1's backcolor property through code how do I then get access to button1, now it's a child-control on panel5 that is a child control on panel4 etc. ??
View 3 RepliesIt is my goal to write a program to run a retail store. I am an intermediate Access developer, so I have a good grasp of the basics.However, I find that developing in VB 2010 is quite different.I will have forms for:

Employee Information
Supplier Information
Customer Information
Invoices & Purchase Orders
All I really need to know at this point is the code to open and close each form.
I would like to know if its possible for my vb.net app to monitor a 3rd party application that it starts. I'd like it to check every 0.5 seconds to see if the child app has a dialog box visible with a specific text string caption. If it does then I want to close my app but if isn't yet visible, keep looping until it is. I'm asking because the 3rd party app has "no event firing when the application starts to load and then displays the dialog so there is no way for the 3rd party app to report back" to my vb.net app when this is loaded.
This came from the Technical Support from the 3rd party app after I asked if using waitforinputidle() in my app would allow me to detect when their app finishes loading and enters an idle state (sadly not). However they have suggested that it might be possible to monitor their app for a specific dialog caption and then close my app but this is beyond my novice understanding just now. How to go about such a process?

I want to program a water supply pipeline network in a treeview control. It has five node (junctions). The parent-child relation is based on a parameter (say pressure). Initially, the node 1 is parent and its child nodes are 2 and 3. The node 3 has child nodes 4 and 5. At run time the pressure changes. Now, node 3 is parent and its child nodes are 1, 4 and 5. The node 1 has child node 2.
