Have One Window (without Child-windows) That Can Have Multiple Content-sets?
May 5, 2011
I would like to have one Window (without child-windows) that can have multiple content-sets.For example: I want to have a set of lables and textboxes to save information for an object (like a person). This person has several sub-items. I want to have a set of lables and textboxes for these sub-items in my mainform too. But I don't want the lables- and textboxes-set of these two objects to be both visible at the same time.

I have an MDI window with multiple child forms. The user can hide or display child windows by checking/unchecking in a View menu on the main form, calling on either the Show or Hide methods for that form. Each time I call the show method do I also have to specify myForm.MdiParent = Me, or do I only have to specify that once, ie does vb remember that the form will always be a child? it doesnt appear to be a form property any more (from vb6).Second question relates to forms themselves. If I have created a form at design time, is it more efficient to create an instance of that form using New, or simply show the form as it is by just loading it.What are the pros or cons, memory and speed wise? In my case I will never need more than one copy of that form to appear, I'm using VB2005.

I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

i have a Janus grid, which has two columns and the rows are organized in a hierarchical order i.e. parent and child rows. One of the columns in the grid is grouped (by dragging the column in the group by box above the grid). I have a cell-changed event that is fired when a cell content is changed. I do this in the cell-changed event:[code]If i change the value, in a parent row, of the grouped column then the child rows are set to Nothing. After the last line in the above snippet, child rows of row are set to Nothing. On the other hand, this problem does not occur if i change the value of the other column (which is not in the group by box). The problem occurs only if i group a column and change its value not otherwise.

I have an MDI application where the child forms are set to sizeable, but when I hit the cascade option the forms are resized. Other than setting the forms to a fixed size is there any way round this?

So here is the situation. I have a button on one of my extjs pages. This button opens a child window as a pop-up. This child window has a .method attribute as well as a .ref attribute, and also a .id. I need the functionality to open another window with the SAME template, everytime I click that button.I was thinking set the childwindow .method property to something like 'getWindow', and the .ref to something like 'newWindow' and then create a javascript function on the backend to look something like this:
var myArray = [];
var count = 0;
function getWindow() {

I have a 3rd party program that puts up a pop up box and asks the user for input. In Spy++ the original program (I'll refer to this as Window A from now on) is a top level window, and the popup (Window B) is also a parent window. However, when I use FindWindow(Nothing, "Captcha Challenge") it returns 0. I've also used a code snippet from the forums

I am trying to find the handle of the child window for the Yes button in the User Account Control window so i can click it. This window has a structure with a few child windows with the same name.
Dim hwnd As IntPtr = FindWindow(Nothing, "User Account Control")
Dim hwnd2 As IntPtr = FindWindowEx(hwnd, 0, "DirectUIHWND", vbNullString)
Dim hwnd3 As IntPtr = FindWindowEx(hwnd2, 0, "CtrlNotifySink", vbNullString)
Dim hwnd4 As IntPtr = FindWindowEx(hwnd3, 0, "Button", "&Yes")
There are multiple CtrNotifySink with its own Button child window or other child windows. How do i search thru the different CtrNotifySink window to find the one that contain the Yes button so i can send a click to it? I do need to find it before i can send a click, right? because i try just sending it to the main window with sendmessage and nothing happen.I even try sending it directly to the handle found by spy++ of the yes button with bm click but nothing happen?

I am looking to close the application when I click a cancel button in a login page, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application. Here's the code that I have so far:

I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
[code]....
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick. I do have the following regex for parts of it.
Detecting the parentheses: (w*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))

I've got an issue with a program I am writing. The specific issue is replacing characters in a parent string by finding, and matching, specific characters within it that are parsed from an external xml file. It's for a chat-like client.Here's the 2 classes I am using to pull the emote strings, titles, and id from external XML:
Imports System.Text.RegularExpressions

I'm still somewhat new to visual basic and programming in general (started teaching myself in December so I could learn how to program), and up till now I've been very successful at troubleshooting my more difficult problems with liberal use of google and forum-browsing. However, this is the first problem I've had that I can't find mentioned anywhere else.In the design view, my form looks perfectly fine. But for some reason—somehow—at runtime the form doesn't line up properly in its window (white space between the border and the grey area where the background begins). I haven't altered the size programmatically, nor have I changed any settings (as far as I know) that weren't changed in other forms as well (this is the only one that's messed up).
I should also mention that I don't have any code that interacts with the form's own design code or events, except for the Load event (where I assign values to three tooltips).
Form in design mode
Form at runtime
The only clues I've gotten to what may be the issue are that if I try to resize the window with the mouse (at runtime), the pointer gets stuck resizing (it can't "let go" of the window). The other clue is that if I click on the white part itself, I'm able to drag the window around (like I were clicking the bar at the top of the window, that I just realized I don't know the name of, which is kind of embarrassing...). Other than that, everything in the form works as it should (including the three half-buttons).

I want to be able to hide the left hand side of the screen and right hand side of the screen at the beginning of the program.
Then when the user presses create new button the left hand side of the screen becomes available so they can create the new item. Then when they press save it comes back to the middle datagrid only.
Then I want to add an event when the double click on the datagrid row (data is programmed in to the datagrid in the code) the right hand side of the screen becomes visible then when the button allocate is pressed the right hand side disappears again just leaving the datagrid.

(vbnet 2008, windows forms)I have a main form (not MDI) with a menu that will open another form as a window on top (I have already set the TopMost property to true). My problem is that it will set this window on top of everything that I open (any program). How can I set this window to be on top of just the main form? I guess I have to declare the main window as its parent, I tried the code below but it didn't work...

Private Sub FilterToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FilterToolStripMenuItem.Click

So I'm adding a tab panel to a child window. A lot of our controls here are user defined but this looks like an ExtJS issue. When I add a tab panel, and then try and add controls and stuff to that panel, everything is cut off on that panel.
Here is the code I am using:
Using ViewDetailsWin As New Pages.ChildWindow
With ViewDetailsWin
.IconCls = Model.WorkflowStepDefinition.SmallIcon
.Ref = "viewDetailsWin"
[code].....
I can't even see the dropdown at all unless I scroll on the tiny little scroll bar it creates. It gives like a quarter inch on the screen to see anything inside the tab panel. There is no size property on the tab panel from what I can see.
