View 1 RepliesHow do i catch an exception for the following piece of code?
If File.Exists(Path)Then
m_TempTable.ReadXml(Path,XmlReadMode.ReadSchema)
I deliberately deleted some code from the xml file to replicate a corrupt file but cannot catch the exception before the program trips up. I want to be able to notify the user there is a corrupt file and get them to re-install it.I have tried trying and catching but the debugger always stops with an XmlSchemaException at - m_TempTable.ReadXml(Path,XmlReadMode.ReadSchema)
The xml file is static information that needs no changing or saving. Would another way of storing this info be better?
I am looking for a way to block registry changes unless I choose to allow them to be made. So basically if an application tries to make a change my program would display a dialog with information of the change and I can either click Allow Change or Disallow Change.
Only thing is I am not sure how I go about stopping a registry change before it happens.
I am using ASP.NET 3.5 and we are having a problem with our website www.s1.com
Also go to other links in the page if you dont see it on the home page.
When you open the site in IE 8 the top menu at first gets displayed like this.
And then the rest of the website loads. What can this be? Maybe a setting on the Server or in IIS?
I have never used a web browser in my programs before and i am not an amateur programmer. I decided to play around with the web browser tool i was trying to set up a simple program that when the web browser navigates to ie: [URL]. After it navigates there is a panel on the side of the program that has two text box's and a button. two text boxes one for email and one for password and after you click the button it puts the text you have in those text boxes and it puts it into the Facebook text box logins. There is something wrong with my code

[code]Close to no real programming skills (PhotoShop artist turning Visual Basic Beginner)This is a snippit of the code used in my browser. Basically the items that are in the list box are loaded from a text file hidden in the installation directory so a manager (or such) will be able to edit which websites are navigate-able.Here comes the problem though, I have not been able to get it to work correctly it will not block any of the listbox items. If I can remember it will only block the site which is selected.How can I re-code it to make the program block all the items in the listbox instead of just one.(Also if not too much trouble how can I make something that will enable and disable the code)BTW this isn't a commercial program or anything just a project I have been working for ever at home.

Is there any way to block the file download dialog from appearing?
Im using the web browser control
So you know what I am talking about:[URL]...
I have built my own browser 9see attached code) however I would like to modify the code so that textbox1 reads a txt file at start and uses the contents of that text file to navigate to a URL of equal value to the text with in that text file. All this should happen at the launch of the web browser form. Example of the text file contents would be [URL] Code as follows:
[Code]...
how to use them then before, but am still a little confused with a few aspects. Here goes:
1.) Lets say you have a method that checks for a certain condition(s) and if it fails Throws an exception. Does it have to be in a try/catch block? Meaning can the "Throw" statement exist in a block with no try/catch statement?
2.) Now lets say we have a method that has a try catch block and in it there is a throw statement. When the throw statement is executed does it first try to find an appropriate catch block in the same method or does it immediately go back to the calling method without looking at the catch statements in the current method where the exception was thrown?
3.) I created a custom exception class that inherits from ApplicationException. Next I created a method which has a catch block that catches this type of exception and does some action. Is the System(i.e CLR) smart enough to throw an exception of this type, or does it only throw exceptions from SystemException?
4.) I know that some people are more liberal in their use of exceptions and others use it more sparingly when truly strange stuff happen like the DB going down. I am writing code where I am getting some info back from the database, converting it and then storing it. Sometimes there might be data that comes back from the database and other times the field is empty and the Null value comes back. Therefore in the instances where Null comes back from the database I should not convert the value to anything, since I will get an error. What should I do in this situation? Should I let the CLR throw the exception when it goes to convert the Null value or should I check for the Null value and if it exists not convert?
5.) In general when I throw exceptions, is it sensible to only throw exceptions of the type Application Exception or are there instances where the programmer throws exceptions of the type SystemException?

I have about 100 PNG images stored in a Resource. Sometimes I need to have the same images in an ImageList, but I do not want to store the images twice in my application, so I add the images from the Resource to the ImageList during runtime when I need them.
Is there an easier way to do this than having 100 lines of code, like the small example below?
imgItems.Images.Add("A", My.Resources.A)
imgItems.Images.Add("B", My.Resources.B)
imgItems.Images.Add("C", My.Resources.C)
imgItems.Images.Add("D", My.Resources.D)
