I know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />
I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.
Is there a way to make the actual error message appear on this custom error page too?
In IIS 5.1, i have set the website security to Basic Authentications and i have set the page for custom error in IIS which is directing to c:est.asp file. When user try to access the website, the user name and password screen comes up and after entering the wrong password 3 times, system shows the custom error page which is fine but why does system prompt for the user name and password again (for three times)?
I don't want user login screen on custom error page. I have tried to put the custom error page on the default website and set the security to anonymous but it still shows login screen on custom error page.
can i change the error massage that appear when .NET Framework is not installed??
View 3 RepliesI've written a class for a new TabPage type.The only thing I've added is a couple variables which I can assign to the tab page in order for my app to identify which tab page is selected.This works fine on my pc, and a few others, but I have one customer who is using my app.When they run, and they open a new tab, the TABcontrols.tabpages.add(NEWTAB) errors out.I'm 100% sure that this is because it doesn't like the fact that newTAB is my custom TAB class.When I did some debugging, his pc moved past the error when I just added a default tabpage type.
View 11 RepliesI am having a problem, which I did not have until recenty, adding personal macro buttons to the Quick Access Toolbar using Excel's Customize function. The macros, which I know are, enabled and executable, cannot be assigned to new buttons on the QAT. Actually, I can add macro buttons to a new workbook fine, but when I close, reopen the workbook, and try to add another personal macro button, they all disappear.
I set 'Show Add-in User Interface Errors' in the Advanced tab of Excel Options and get this error when I open a workbook with personal macro buttons added to the QAT[code]...
I deleted the macros and manually keyed some simple command (msgbox 1) into a new macro and still got this error message.
I set 'Show Add-In User Interface Errors' on a remote server (where I do not have this problem) and I do not get this error message when loading workbooks with customized QAT.
When debugging a program, instead of doing this on EVERY piece of code:
Try
MyFunction()
Catch ex as Exception
MsgBox(ex.Message)
End Try
Is there a way to apply that to everything error I encounter without writing it on every function/sub/etc?
In asp.net, I can define a custom error page like this:

I have created a Custom control, containing 4 masked text boxes.and most times when i build it, i get a error: "InvalidArgument=Value of '-2147483648' is not valid for row position.' What is it? i searched MSDN, it looks like one of the SQL errors. How can this happen, i didn't use SQL.Edit: i fixed this tool strip problem. seems that i put visible to false unknowingly. I also have a problem with my Tool strip. The tool strip on the top works well, but the one i placed in a table layout panel, is missing from view, it only appears in Design view when i select it from the bottom strip.
View 4 RepliesI'm making a class that reads a file and processes data in it, but I need some error handling. I'm giving it a constructor that takes a file location and processes that file. How can I make it so the constructor tells the program whether it found the file or not? Optimistically the program that calls this class would check for that first, but since I'm not going to be the only one that uses this class I'd like to know how to secure such a thing. It's probably bad practice to do this within the class, but I'd like to be sure it's as portable as possible.
View 6 RepliesI have a windows application created using Visual Studios 2005.I recently added a custom control - after I built it, I was able to see it on the toolbox and I placed it from there to my form. All was good till at some point, when I tried to go to the design view of my form that the control is on, I get this error: Could not load file or assembly 'acdbmgd, Version=17.2.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. [code]I can still run my app and see the control that's on the form, but I'm wondering what this error means? If I rem out the code behind my custom control, I can then view the control on the page again when I design the form.
View 1 RepliesI have a MouseEnter event which currently handles some custom controls on my form. The program is a card game. I have a collection (handCards) that gets populated when the user draws a card and then it adds the latest card to the form. This collection holds cards of various custom types, all which inherit from picturebox. Drawing the cards from the deck and adding them to the form works fine. The trouble I am having is that at runtime, after a card is drawn and added to the form, I've created an addhandler line of code to have those cards respond to my MouseEnter event, but my addhandler line of code is telling me that MouseEnter is not an event of object. How can I get around this so that after a card is drawn and added to the form, when the mouse enters the new custom control, my MouseEnter event fires? Here's one of the many things I've tried and what I think should be the simplest and easiest that should work.deck.DrawCard()AddHandler handCards(handCards.Count).MouseEnter, AddressOf Cards_MouseEnter
P.S. the MouseEnter event works fine for custom controls that are on the form prior to runtime and all it does is take the image of the control and enlarge it by placing the image to a bigger card on the form.
My job is requiring some visual basic programming and i've only programmed in C#.So i have this code:
Public Custom Event Command As JQDialogEventHandler
AddHandler(ByVal value As JQDialogEventHandler)
commandHandler += value[code].....
I'm getting the error: Operator '+' is not defined for types 'ControlesModificados. ControlesModificados.JQDialogEventHandler' and 'ControlesModificados. ControlesModificados.JQDialogEventHandler'. How can i write this code "commandHandler -= value" in other way so the error goes away! or how can i defined those operators for the eventhandler.
Namespace ControlesModificados
Public Class JQDialogButton
Inherits Button[code]....
As you can see the DialogCommand is using another JQDialogHandler, so i can't just use
Public Custom Event DialogCommand As JQDialogEventHandler
I am trying to implement a Custom HttpHandler (for the first time), I have been given a tutorial to follow but couldn't get it to work. I then found another tutorial but couldn't get that to work, they are both giving me the same error message.
The custom handler is to protect people from downloading certain file types, although i think the error is somekind of configuration problem as I can't get the website to work at all once I add the httpHandlers to the Web.Config file.

When I run the page, there is no validation and no error message. Please can you point out where I am going wrong, I'm suspicious it is at Page.Master.FindControl("form1").Controls.I have previously done such validation by looping through controls via form1.controls but this is unavailable as the page uses a form passed down via the master page.

I have developed a windows based application using visual studio 2005 called DMS. On the client side, this application runs on asp dot net framework 2.0. We have created its setup file which has to be installed on the client pc. After the installation of the application, some of the users get the error message as:
DMS.exe - .net framework initiation error Unable to find a version of the runtime to run this application
(I have also attached the screen shot of the error message.) Trouble shooting done by me:
a. I had tried the re-install Dot Net Framework 2.0.
b. Scanned the PC for virus attack.
c. Install dot net framework 2.0 first and then the application.
d. Un-install and re-install the whole application.
But none of the solution works. The only thing that works temporarily is un-install the whole application and re-install it. Then it works for a few hours.

I never got into detailed error processing too much when I played in VBA/VB6 a lot. Mostly then, if you ran into a user error (such as some input of theirs failing a validation test of some kind), you popped a MsgBox() with some error information and the critical (or warning) icon, and safely aborted out of the code
In .NET, my reading basically points to exceptions as the end-all in error handling. It looks to me that if you know a spot of code where a user can screw up, you're supposed to catch it with either try...catch blocks (for things like data conversions), or standard if...the...else constructs for other things, and then throw a new exception if needed.
Isn't throwing an exception essentially a forced crash of a program in a sense (granted, you get the option of continuing)? Or are exceptions geared specifically for things like data conversion errors and other "things that shouldn't happen", and resume use of MsgBox() and friends for minor user screwups?
Consider the case of where you have a TextBox that is only supposed to accept numeric data (or heck, just a specific set of characters). Barring some other trick that lets you restrict that field (let's just assume it's freeform, programatically), it would seem a bit of a waste to throw new exceptions everytime they type in an invalid character, or even if the error checking doesn't happen until they press a submit button (like on a webpage). Popping a MsgBox() seems more sane in that case.
So what's the straight dope on exceptions and throwing new ones on user errors? How about if your program also exposes a programmatic framework? Bad usage of one of the programmatic functions definitely seems like new exception territory to me.
