Asp.net Mvc - Why Is ValidateInput(False) Not Working
Apr 30, 2009
I am converting an application I created using webforms to the asp.net mvc framework using vb.net. I have a problem with one of my views. I get the yellow screen of death saying "A potentially dangerous Request.Form value was detected from the client" when I submit my form. I am using tinymce as my RTE. I have set on the view itself ValidateRequest="false"I know that in MVC it doesn't respect it on the view from what I've read so far. So I put it on the controller action as well. I have tried different setups:
[code]...
Just to see if it made a difference, yet I still get the yellow screen of death. I only want to set it for this view and the specific action in my controller that my post pertains to. Am I missing something?

I have a form that has 13 groupboxes each with 6 radio buttons in them. I want to be able to tab through the left-most radio button in order. At load time, the left-most radiobutton in the top groupbox is checked. The only way I found to have this load unchecked is by setting it using a timer, but this makes it so that that radiobutton can't be tabbed to at all.

I wanted to create my own type that acts like the Boolean type, except I wanted to use Yes and No instead of True and False.I kind of got close but it wasnt exactly what i was going for here's what i have:
[code]...
so i have to use an integer when i dim it like:dim b as MyBool = 1 then when you look at it in the watch window b = {Yes} so i could settle for that, but with a boolean you can do this:dim b as Boolean without setting it to anything it defaults to False mine however, is Nothing. 2 things: 1. How can i get mine to default to No 2. How can i make it work like this: dim b as MyBool = Yes instead of having to use the integer this is not a requirement for anything I just wanted to know how to do it

I am not sure why I can't use pictureboxes when its visibility is set to false?? While the picturebox is not hidden, as part of my game I want the user to be able to guess where the picturebox is which means by clicking on it, it should trigger an event but even when I set this event, nothing happens. When visibility is set to true then the event triggers.
I want to be able to trigger events even if visibility is set to false,

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

coming from this question i was wondering why:
[Code]....
'this throws an "Object reference not set to an instance of an object"-Exception'
[Code]....
A CType(obj, Boolean) would evaluate to False(just as CBool(obj)), i think because the compiler uses a helper function, but that is not my theme. Why does casting Nothing to Boolean evaluates to False, whereas casting an object that is Nothing to Boolean throws an Nullreference-Exception? Does that make sense?

Its my understanding that by adding the ScaffoldColumn(false) annotation to an property in a class, that property will not added to the view when doing Add View. However even though i have added scaffoldcolumn false to properties i dont want added to a Create form, they are still rendered inthe create view. Is ScaffoldColumn broken? On page 552 in Pro ASP.NET MVC 3 Framework by Freeman and Sanderson, it states "If we want to exclude a property from the generated HTML, we can use ScaffoldColumn attribute. When the scaffolding helpers see the ScaffoldColumn attribute, they skip over the property entirely; no hidden input elements will be generated and no details of this property will be included in the generated HTML.
" Also the MVC Music Store PDF on p 77 indicates that the attrtibute will do the same -"Allows hiding fields from editor forms".They add it to the AlbumId property and then when the app is run AlbumId field is not shown in the browser. Is this attr broken?If i change a html helper to DisplayFor it does not appear in the form regardless of whether scaffoldcolumn is present. For example i dont have scaffoldcolumn false on Property PostTitle but if i change @Html.EditorFor(Function(model) model.PostTitle) to displayfor then it does not render regardless of the scaffoldcolumn attr. Also my Create view is strongly typed to @ModelType RiderDesignMvcBlog.Core.Entities.Post?

I have an asp:checkbox control on an aspx page I am working on. This checkbox is within a custom control and previously was posting back every time it was clicked. I am in the process of ajaxifying the page and have come across a problem. When I remove the attribute AutoPostBack="True" from the asp:checkbox, the vb code returns False when I check myCheckbox.checked (this is on a postback else where on the page what has not be ajaxified), even though I can see the box is indeed checked.
I am assuming that because the checkbox no longer posts back, for some reason the VB code (or the view state maybe) doesn't see it as having been checked. Is this correct, and if so, how to I correct it?

From what I can tell, the main purpose of a PagedDataSource is to allow paging of a datasource before being bound to a server control.
If this is the main purpose of this control, why is the AllowPaging attribute's default value False?
I'm only asking as often I will forget to set this as True causing confusion when it doesn't work.

Simple question, I have an application and dependant on whether you are in the administration system or on the public website I want to show different results. Example: in the database for a news story in the administration I may set the column value 'showonsite' to false. So I would like this to show in the administration panel only and not on the live site.
My question is, because I require the same information just with the only one column change, live site to only show true values and administration to show both. What is the most effective way of achieving this without copy paste of code?

I created a SRT program in vb6. works great. I thought it would be a good time to port it over to vb2010 for obvious compatibility issues. the following will not work, even though through debug; all the vars are correct - it just wont come up.
' Timer1.Stop() : MsgBox("start: " & CaptionStart & " end: " & CaptionEnd & " smptime: " & WMPTime) : End
If (CaptionStart <= WMPTime) And (WMPTime <= CaptionEnd) Then
txtCaption.Text = Caption
'// HIGHLIGHT IT IN THE LIST
[code]....
in the above its simpler (why I like vb6) and works perfectly. I am most likely "not seeing the forest for the trees" syndrom.

I'm reviewing some code in VB.net, and in a validation object they have written the following
If Not IsDate(Entity.SelectedDate) Then
ErrorList.Add(New CValidationError("MainReport", "Please select a weekend date"))
SelectedDate is of type Date. It seems to me it would be impossible to ever hit this condition. Is this true?

I am trying to get true false statements to work. Each statement has its own msgbox and if true adds 1 to x. At the end i use a case function which will give the final number of x and give it a value in a textbox. What is happening instead is, if I click "no" on every Yes/No question, I get a 4. If I click "yes" on every Yes/No, I still get a 4. For car 3, 4, and 6 I want a "no" to be true. For 1,2,5,7 I want yes to be true.
HTML Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClick.Click

Am using asp.net for above 5 years. But now am facing a weird problem. When i try to send emails from form created by me which contains asp:button, asp:textbox, etc., in code page it always telling IsPostBack false. Even when i click the Send mail button(asp.net button). I cant understand what is problem.
Is it anything needed in web.config file for postback??[URL]... Am sure its not problem in Test page.Because it is very normal page which have only one button & code in vb. Problem somewhere in cache, urlrewrite or web.config. But i cant understand where?
[Code]...
When i exclude that dlls and remove the httpmodule line from web.config file postback working fine. So this is error. They done something wrong in their Dll files or httpmodule.
But still can't understand what is error. Is it have chance to control postback action from dll files?
