Iterate The Parents Hidden Controls Names, Get Their Handles And Then Activate Them One By One?
Aug 24, 2010
I have an application and Spy++ reports that the parent window has many controls that are hidden. When I do a mouse click on the application's window, a number appears and I suppose it's the hidden controls that change their text/picture.So, is there a way to iterate the parents hidden controls names, get their handles and then activate them one by one (with sendmessage/postmessage wm_buttonclick) to see what changes?Right now I get the windows handle with FindWindow and the window's process id.

I need to iterate through controls using dynamic construction of control names and it looks like this could be what I need, however I never used this before and it does not quite work. What am I doing wrong? GroupBox1 is what I am attempting
Dim x as Integer = 1 For Each ctrl As Control In CallByName(Me, "GroupBox" & CStr(x), CallType.Method).Controls The runtime error is "GroupBox1" not found on Form1 even though I can select Me.GroupBox1 from the dropdown list.

I like to build objects that contain properties and also functions / subs to do work. I dont have a lot of other programmers around me to answer this question so I thought id ask. If my goal is to make a function or even sub part of a class blue print is it better to do it by making a seperate class for the function, and then construct a new copy of the classFunction as a property of the parent class or is it better to simply put the function in the parent class.

I'm trying to create an export Excel/CSV function that will iterate through a custom object and first output the property names and then output the values. I want to use reflection only where necessary so I'm attempting to save the property names when I output the headers and then reuse them to print the values. Is this possible? I'm a little weary of using reflection in a loop but is there a better way?

How do I find out the hidden excel sheet name using ADO(OLEDB) in C#? In My Excel workbook there are a lot of sheets. Only one Excel sheet is in hidden mode. I need to find out the names of hidden sheets. My code finds both hidden and visible sheets.This is my code to find excel sheet names for all sheets. Is it possible/can any one tell me how to find out hidden excel sheet names without using Interop services in C#?

I have a simple XAML file with a grid in it and textboxes. But when using my code it does not find the textboxes by iteration.
VB.Net:
Dim ctl As FrameworkElement = Me.MainWindow
Code:
Dim ChildrenCount As Integer = VisualTreeHelper.GetChildrenCount(ctl)
'ChildrenCount is always zero
For i As Integer = 0 To ChildrenCount - 1
Dim Child As FrameworkElement = VisualTreeHelper.GetChild(ctl, i)

What i want to do is grab the handle of a webbroswer control and only read the co-ordinates within those bounds. I have successfully manager to do this but the problem i am now having is moving the mouse to those co-ordinates, for some reason after getting the handle and moving the mouse:
Windows.Forms.Cursor.Position = WebBrowser1.PointToClient(New Point(x, y))
It still reads full screen co-ordinates.

I am new to using Visual Basic 2008. I have been programming in VBA for years. In VBA I used the following type of 'For ... Next' statement to go thru multiple controls in a form which are named the same except for a number at the end of the control name. [code]...

I am already overriding the SnapLines property in my ControlDesigner-derived class to manually forward out various snaplines from the child controls of my control -- the text baseline (pink) snap from the labels and comboboxes; the text inset snap from the labels; the top, bottom, left and right snaplines from the comboboxes. Those snaplines activate when the control itself is moved around on the form and when other controls are moved around it.
What I need is the ability to tell the designer to activate the snaplines and then deactivate them while I'm doing an internal move or resize of the underlying controls.My comboboxes are resizable through overrides of OnMouseDragBegin, OnMouseDragMove, and OnMouseDragEnd in my control designer. The magic bullet I'm looking for is something I can call in Begin to tell the designer to show the snaplines and something in End to tell it to stop.
Allowing people to resize and move the internal controls at design time is kind of useless if they don't show snaplines for each other or for external controls.As with stuff like this, it's incredibly hard to search for. I've found one post on a forum where someone asked this exact question that had (of course) no responses. That's about it.

I have a windows form that I bind to a datatable via a binding source. The binding is done in code at run time. Eg;Me.txtCode.DataBindings.Add(New System.Windows.Forms.Binding("Text", bsForm, "ToolCode", True)) (bsForm is the binding source)This works well except if the form control is hidden (I have a couple controls on the form that hold Record ID and Version numbers that the user doesn't need to see). Databinding doesn't seem to work reliably for hidden controls.

I am wondering if anyone has any idea how to make the controls stack and fill up the available space left by a control if the control is hidden or removed from the UltraGridBagLayoutPanel.
Example:
[Textbox 1]
[Textbox 2]
[Textbox 3]
[Textbox 4]
[Textbox 5]
If I hide [Textbox 3] as of now, it will disperse the space left equally and pad the remaining text boxes with the space. However, I would like it to do this...
[Textbox 1]
[Textbox 2]
[Textbox 4]
[Textbox 5]
Where all the text boxes will move up and [Textbox 4] will completely consume the space left by [Textbox 3].

I am using MVC3 and EF 4.1 (Oracle DB). Let's suppose I have:
Public Class Parent
Public Property Id As Integer
Public Property Name As String
[code]....
I want to retrieve all parents from the database and for each parent I can access its children.I want to do the following:
Dim firstParent = (From q In db.Parents Select q).First()
For Each child In firstParent.Children
'Do something
Next
The problem is that I would like to enumerate the children from the youngest to the oldest. Is it possible without the client-side sorting? If yes then how can I achieve that? I know how I could achieve what I want with an SQL query, but I cannot make it work with LINQ...
EDIT:Since this seems not to have a solution in my case and sorting everytime I request data is not an option, maybe there is something I can do when I insert the data to the database? I do not have a control on which order EF saves items to the database when I call db.Save(), but maybe there is some syntax I could use to require ordering based on some property.

I know generally it is not the best solution for a child to handle an event of parent. Take this for example; Mainform loads UserControlOne, UserControlOne handles all UserControlOne needs to. How ever we need a MenuStrip/ToolStrip. MainForm does not need to know much about what UserControlOne is doing. Other then receive some information on a statusbar. Right now events are controlling this.
The menustrip/toolstrip need to be able to speak to UserControlOne, for example when buttons are clicked on the strips. Would you; Allow the child to add a handler to capture the parents event? Move the MenuStrip/ToolStrip/StatusStrip all to UserControlOne so we can ignore all this event hassle? My Major concern with this is now we have taken all the head ache away from MainForm and crushed it into UserControlOne. Any suggestions?

I have a Dialog which I'm calling via Loading.Show()Can I lock the position and location to the parent form? In such a way so if the parent is minimised or moved, the child will stay centred to the parent?
I was using ShowDialog() but this obviously stops the parent from being accessible. This is being used to display a progress gif. (Child is 50% opacity)

I have a big problem regarding MdiChild. My problem is that I have 3 forms loaded;
Form1=Mainform / mdiParent
Form2= Display the Datagrids
Form3= This is where I let the user input the necessary fields like Lastname, Firstname,Age,etc...
My problem goes like this, Form3 is the child of Form2, Form2 is the child of Form1 and I call them one by one like this:
//form1
Form2.MdiParent = this;
Form2.Show();
[code]....
I want in the Form3 to save data and refresh on my datagrid on Form2 so that every data that I encoded in Form3 will reflect in Form2. I let the Form3 close everytime there is data entered but my problem is that the data that entered doesn't reflect in my datagrid.

I have an aspx page which houses an iframe. When a button is clicked, a WCF is called to produce a PDF which is read into a byte array. I was storing the byte array in a Globals.vb file like this:
Public Shared PDF_Data as Byte()
The global was loaded from the parent aspx page like this:
PDF_Data = MyWCF.Create_PDF_File(SomeVariable)
After that, the iFrame's src was set to a blank aspx page, which had the following code in the page_load event:
'Write the PDF binary data to the screen (viewer)
Response.Clear()
Response.Buffer = True
Response.ContentType = "application/pdf"
Response.BinaryWrite(Globals.PDF_Data.ToArray)
However, realizing that this application will have several users who will get different PDF documents, I have learned that this is not the way to go. My shared variable would be accessible to all users, a big no-no.However, I am stumped as to how I'm going to store the byte array and make it available to a child aspx page from it's parent.

I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?
