This is a common design to get round name collision issues. Basically, you can have two files called Document1.doc from different users - you can only store one of these in a directory, so you need to generate a unique name and associate this with the document. In other words, you rename the file from Document1.doc to your guid named file and you have a mapping in the database that shows the original filename and the new filename.

First of all it is not a C# question. You must post questions in the appropriate forums.
Solution: When you click on publish it must have asked you for the path. Try changing the path. And then copy the path and see that do the files exist after publishing.

Well, I didn't know where should I ask my question, so I ask it here! 
I'm willing to know what exactly happened (for OS and whom it may concern!) when a running application calls a function or a sub or a method?
And is there any way to get the name of that function or sub or method?
Thanks.

Usually the function's (or sub's or method's) code is executed.

Of course.

hi there... I have one problem, and I cannot solve, so any help will be appreciated. I have a datagridview control on a windows form. I am using the form for retrieving data from a local database, and then cleaning up the selected data. So I want to add a checkbox column, when the user will check the checkbox, that would mean that the row is selected, and he can delete just the checked rows. How I can do that, any help? Thx

Add a checkbox column to your grid. When user clicks on delete button or whatever for deletion, just filter the rows which have the checkbox checked and delete them.

the thing is that I am creating a datagridviewcheckboxcolumn control on runtime...I want to know how to create an event for the control, cause I cannot get properties window for the control, because I am creating the control on runtime. I want to add a CheckedChanged event. How I can do that? Thx in advance

This is going to be dumb, but I can't figure it out for the life of me. I am using placeholders in a global resource file, I have found that the string is too long so I want to put in a line break dynamically, now since this is multi lingual the break may need to be in different places depending on the language. When I enter "
" as one of the placeholders it encodes the text which makes the HTML not render no matter what I do. I have tried to decode it, but that didn't work. My string looks like this Results for room {0}.{1}All shown rooms are suitable for {2} adults and {3} children Here is my code (the br may not show up)
divResultsHeader.InnerText = string.Format(Translate("resultsHeader"),
RoomNum.ToString(),
"<br />",
infoObject.ReservationRoomInfoList[RoomNum-1].NumberAdults.ToString(),
infoObject.ReservationRoomInfoList[RoomNum-1].NumberChildren.ToString());

Use the InnerHtml property instead of InnerText.
Despite everything, the person most likely to be fooling you next is yourself.
|
|
|
|
|
That didn't work, it's still encoded the br tag.
|
|
|
|
|
Then you did something wrong. What does the code look like?

Looks exactly the same as I posted earlier but I changed InnerText to InnerHTML. There should be a < and > surrounding the br tag, when I post that in here it actually puts a line break, but this is exactly what I have in my code. The Translate function just gets the string from my global resources file.
divResultsHeader.InnerHtml = Server.HtmlDecode(string.Format(Translate("resultsHeader"),
RoomNum.ToString(),
"br /",
infoObject.ReservationRoomInfoList[RoomNum-1].NumberAdults.ToString(),
infoObject.ReservationRoomInfoList[RoomNum-1].NumberChildren.ToString()));

You are obviously not seeing the result of that code. Check that you are actually watching the page where you change the code, and that the page is not cached.
I tried this code in code behind:
int RoomNum = 42;
int NumberAdults = 2;
int NumberChildren = 1;
divResultsHeader.InnerHtml = string.Format(
"Results for room {0}.{1}All shown rooms are suitable for {2} adults and {3} children",
RoomNum,
"<br/>",
NumberAdults,
NumberChildren);
The element in the page markup code looks like this:
<div id="divResultsHeader" runat="server"></div>
The resulting code in the page looks like this:
<div id="divResultsHeader">Results for room 42.<br/>All shown rooms are suitable for 2 adults and 1 children</div>
Despite everything, the person most likely to be fooling you next is yourself.

You are right, during testing I was messing with encoding and decoding so I rewrote the div using an innertext. Thanks for your help.

Hi, Whatever i can do in vc++ can it also be done in c#, or is there any thing which is done in vc++ but not in c#???????
|
|
|
|
|
Well, C++ code can run without the .NET runtime, so that's one thing.
Why do you ask ?

i want to know which is more powerful c# or vc++. and is microsoft still supporting vc++ or vc++.net.
|
|
|
|
|
Well, this can be a bit subjective. VC++ was designed to extend the power of C++ with ready to use visual components(technically MFC and SDK).
That means, using VC++ you can do more low level programming compared to C#.
C# on the other hand is generally considered a better option for RAD(Rapid Application Development).

DateTime? deathTime = null;
if(DateTime.TryParse("somedate",out deathTime))
else
The above shown code won't work as DateTime.TryParse accepts DateTime, not nullable DateTime. So how do we parse a nullable datetime ?
I made it working by the below code, don't know this is the correct approach.
DateTime tmpDateTime;
DateTime? deathTime = null;
if(DateTime.TryParse("somedate",out tmpDateTime))
deathTime = tmpDateTime;
else
Any ideas ?
