i'm working on a program and i'm working with panels, and i'm very frustrated because I want to bring a panel to the front of the form but because of its parent it is locked into another panel.... in the properties for the panels there is no Parent container option though the only way i know how to modify parents is during runtime like this Panel1.parent = Me

View 11 RepliesI'm making a custom control that can be dragged around and it is semi transparent. I need it so that while it is moving (the mousemove event) that if it intersects a control that its parent becomes that control. I tried to have it iterate through all the controls and if control.bounds.intersectswith me.clientrectangle then me.parent = control type thing, but it did not work.
View 1 RepliesI 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.
View 7 RepliesI migrate between C++ and VB.NET in my coding ventures... which leads to the occasional confusion about when something is by value or by reference in VB.NET.Let's say for example that I have an array of MyObject which is populated with a bunch of objects.
dim MyArr(5000) of MyObject. let's say that the information from this array travels throughout various data structures:
dim MyList as new List(of MyObject)
for i as integer = 0 to 5000 step 1000
Mylist.add(MyArr(i))
next
Under the above scenario, I believe everything is by reference. If I extract an entry from "MyTable" and modify its MyObject Members, I think that the original in MyArr will be modified.However, I have run into situations where I thought something was by reference, and it was by value. Are items always added to containers by reference, or are they sometimes added by value?
How do I go about looping through all the controls within a container, and all the controls in the container of a containing control, and so on.

The following only retrieves -Panel and none of the other controlsFor Each cntrl As Control In Me.Controls Next How can I retrieve them all in a For Each loop without an If/Then for every level in the stack?

This is so far the best method I found of doing this.
i have a treeview which has a bunch of parent and child nodes preset at design time, there is 1 parent node tho which is called developer, that i want to add child nodes to at runtime.When the form first loads im trying to have it check a text file and for each line in the text file add the text/string from that as a child node tot he 'developer' parent node.
vb
Dim reader As String = My.Computer.FileSystem.ReadAllText(Application.StartupPath() & "ConfigDevs.txt")
Dim strs() As String = Split(reader, Environment.NewLine)
For Each s As String In strs

Thats what i have so far, how can i set it so 'Dim parentNode As TreeNode = ' points at the 'Developer' node?

View 4 RepliesBeen doing web development for the past 2 years - so I'm a little rusty (and I just switched to VS 2010 from 2008 so maybe something new is available)... I have 4 toolstrips floated to the top of a form. And I have a picturebox below - filling the whole form. Unfortunately the picturebox is "behind" the toolstrips. I want to split the form so that the top of the form holds the 4 toolstrips and the picturebox appears below them.
What would be the proper container to put this mess into so that autosizing is the easiest? The toolstrips will most likely be "turned off and on" during the running of the app.

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.
dim l = Mainform.subform.listofdata

View 6 RepliesI have a core EXE I wrote to serve a series of purposes. Another editor that goes along with it needs to repackage that EXE along with the script that EXE interprets. That is simple enough.
However, I need to give users of this stuff the ability to give that repackaged EXE an icon of their own choosing, but they do not have the source code to manually compile that EXE.
I know some magic with file streams and binary manipulation could do this, but I have the sinking feeling that that's pointlessly doing this the hard way and there may be a better way. Maybe the EXE itself can reset its own app icon per instructions given to it.

I am populating data form database in combobox. This data is in the form of numeric codes like 112, 113,
The thing i want to do is on selecting some code like 113 from combobox, it will display it as ABC113 in the combobox.if code like 114 selected from combobox, it will display it as ABC114 in the combobox.
I don't want to store this modified string in database.
Please help me to achieve this.
Provide me some sample code or link for simple combobox or combobox in datagrid.
i think there is no change in code in both above cases.
I have a ComboBox that is bound to a List(of T).Now I type-cast the ComboBox.DataSource into List(of T)and add some more elements in the List.The items collection of the ComboBox doesnt get reflected and the new element does not show up in the ComboBox. Am I missing something ?

I am modifying an existing application in VB .NET. In one routine, I have added a reference to a class in a newly-referenced class library project that is part of my solution, and now I get run-time FileNotFoundException messages when the program attempts to access this routine while debugging. The error tells me that the class can't be found, what's up with that?
To be clear: If I remove the lines of code relating to the new class, I no longer receive the exception messages. If I add them back in, here they come again! I have referenced the class library in the project containing this routine. The class library is building properly (other projects reference same library, and use it more extensively), and the project is referencing the class library's .dll file in my "debug" folder. I get no errors from other routines that use this new class (thus far). I get no errors in the Error List of the IDE.
