Call '.dispose' On Objects Inside Functions?
Jul 22, 2010say you have a sub containing an io.streamwriter. That streamwriter is declared and used only inside that sub (and not as static). Should you still call dispose on that streamwriter or is it disposed automatically as it is no longer in use after that sub, until you call that sub again?
View 2 RepliesASP.NET Wizard Step Scroll Position
Oct 21, 2011I have an ASP.NET form with multiple steps (using the Wizard control). When advancing to the next step, I want the page to start at the top, but for some reason it is maintaining the scroll position. I set the Page.MaintainScrollPositionOnPostback property to false, and I have the next button event handler set it to false also. I don't have the property set to true anywhere. But it is still maintaining the scroll position. What could be the issue here?
View 1 RepliesAsp.net - Step By Step User Interaction Pattern?
Jul 1, 2011I have a wizard where users need to fill out data. You cannot navigate to the second step until first step is completed.
I enforced this behavior by disabling/enabling "Next" button, but I really do not like this solution, since it seems not really elegant or safe here. What is the good approach on building step-by-step processes with enforcing step completion.

View 4 RepliesAsp.net - Adding To Page Control Collection From Inside A User Control?
Feb 12, 2011I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."

User Control - Adding Internal Labels Inside It
Mar 8, 2010I've made a user control and have added some internal labels inside it. In the User control class I'm trying to handle the mouse events so that: When the mouse enters the User-Control the background of the User-Control turns white - using MouseEnter event. When the mouse leaves the User-Control the background of the User-Control turns grey - using MouseLeave event. However as soon as I move the mouse over the internal labels it triggers the MouseLeave event. I don't want it to do that, because the mouse hasn't left the bounds of the User-Control! So, how do I get it to not trigger the MouseLeave event when the mouse is still internal to the User-Control?
View 9 RepliesCall Button Event From One User Control To Another?
Oct 28, 2011I have created two user controls (lets say A and B) and calling then on default.aspx. Both user controls have button named as clear and its event method "btn_clear_click (sender,event)". Actually I like to do something like this: if I click clear button of user control A then it would also do the same tasks defined in user control B's bth_clear_click method. Means, is there any why to call button event of one user control in another user control.

AxMediaPlayer Step Function Doesn't Step Backwards
Nov 10, 2011I have a program that plays a video and uses the step function to move frame by frame backwards and forwards through the video. The forward frame works just fine:
AxWindowsMediaPlayer1.Ctlcontrols.step(1)
However, the backwards step (below) jumps a full second backwards while the forwards step only steps .033 seconds forward (presumably a single frame).
AxWindowsMediaPlayer1.Ctlcontrols.step(-1)
I can't find any documentation about this problem online and in fact I can't find much mention of this function.the documentation does say the -1 command should step back one frame. IWMPControls2::step method Is this a known bug or is there an updated function I should be using?

View 2 RepliesShould All Subs & Functions Always Be Inside A Class
Oct 4, 2008This is very basic about the layout of classes, subs etc. 1. Should all my subs & functions always be inside a class? I haven't used classes too much before, mostly just a bunch of subs in a form file. Now I downloaded a sample program which I want to develop. This has all the code of the form inside "Public Class Form1": [Code] The code is an example of use of the ZedGraph library. It produce a simple window with one graph/chart. Now I want to develop this code with several tabs, a dusin different charts, file I/O and so on. I'm ok with most of the specific coding, but my question is on the general coding;
2. Should I continue my subs&functions inside this form? inside this class? inside a new class? Earlier when I've NOT been using class, I can make global variables by placing the "Dim" outside the subs. This does not seem to work within a class. 3. Should I avoid global variables all together, or how is this done without always passing arguments?
Also I will make more forms, for program options etc. 4. Should these forms be coded as classes? or just subs&functions in a form? Obviously I'm not well trained on the proper use of classes and have trouble to find this easily explained.

View 2 RepliesVS 2008 : Throwing Errors Inside Functions?
Aug 8, 2010I'm familiar with Throw New Exception(), and how this causes an application to "break" with an error at the Throw line itself.But what I'm after is a way to throw the exception within a function, and for the application to break at the line which called the function - not at the Throw statement itself.Is there a way of doing this, but without having to wrap the function call within a Try-Catch?
For example:
1. Main code calls function "DoThis()"
2. DoThis() runs and throws an exception
3. Code breaks at "Call DoThis()"
Call Module Functions Directly In .NET?
Apr 29, 2010I have a Util module in my VB.NET program that has project-wide methods such as logging and property parsing. The general practice where I work seems to be to call these methods directly without prefixing them with Util. When I was new to VB, it took me a while to figure out where these methods/functions were coming from. As I use my own Util methods now, I can't help thinking that it's a lot clearer and more understandable to add Util. before each method call (you know immediately that it's user-defined but not within the current class, and where to find it), and is hardly even longer. What's the general practice when calling procedures/functions of VB modules? Should we prefix them with the module name or not?
