No, you are right.

Hi All,
I am fetching a dataset from the database under some condition. After this I create a data table. Traverse in the original dataset & add each row to created data table as it is through LoadDataRow method. After adding the row I just update 4-5 columns out of 20 columns in the row. After entire looping I fire the AcceptChanges method on data table. After this I am trying to update this data back to database in two ways -
1) Merge the above datatable to the original dataset & update it back to database through the data adapter. The data adapter I used in one case was the same with which I filled the original dataset. And in second case I created a fresh data adapter & tried to update.
2) In another method I just tried to update the created data table as it is to the database.
I have also created the appropriate commands for the data adapter through command builder. But unfortunately even after getting no errors on the Update call of the data adapter there are no records getting added to the database. Besides the fact that the merged dataset reflects the added rows in the count as well in the dataset items.
Any kind of pointers are dearly welcome.

Hi all,
i made an installer package (.msi file) for my C# windows application. But, whenever i try to install it on the other systems, it is saying "application failed to initialize properly"...
After searching, i found that it works only on the machines where .net framework was installed..
Is it possible to include .net framework in my package & give it that to my client??
Any solutions plz.............
Thanks in Advance.

How did you make the installer package?
If it's via visual studio then right click the stup project and select 'properties'. Form there you have 'prerequisites' in there you can select what your setup depends on.

Hi, thanks for the reply. yup, problem solved.. 
and, how can i create desktop shortcut?? coz i didn't find any "create shortcut" option .....
|
|
|
|

just create a .lnk of the file you want to make the shortcut for and while installing, copy it to either the current user's desktop folder/start menu or to All users' desktop folder/start menu folder.

.lnk file ?? how to create that ?
|
|
|
|

Shortcut file
and store it as a file in the installation package, "That's what i usually do for installation"

OMG! but how???

I'm not sure how your application looks like but if you are intending to copy the shortcut file from the solution "not using an external DOS batch file" then add a reference of visual basic library to your code and use something like this code:
Microsoft.VisualBasic.FileSystem.FileCopy("YourShortcut.lnk",System.Environment.SpecialFolder.DesktopDirectory+"\\YourShortcut.lnk");
also take a look at your C:\Documents and Settings\All Users\Desktop folder and if you want to use this one, try something tricky like getting the drive letter on which windows is installed and concatenating it with the destination path
string strWindowsRoot = System.Environment.GetFolderPath(System.Environment.SpecialFolder.System).ToString().Substring(0, 3);
I hope you get over it ..

Under the "File System" view you should have various folders representing the file structure of your target machine.
i.e.
Application Folder
User's Desktop
User's Programs Menu
If you wished to put a shortcut on the desktop you would select 'User's Desktop', then right click the details panel (which has Name|Type at the top) and select create shortcut. You can then select the included file you want to shortcut too. For anything outside of what your installing you'll need to make a shortcut as you normally would in windows and then include the file using Right Click then Add File.

I have tried it already.... when i rightclicked on "user's desktop" there isn't any 'create shortcut' option.... instead, i hv createshort to user's desktop option: it is creating the shortcut for "user's desktop"......

Hi my problem is my application is one online exam type like quiz application.
Every is attended only one time if they want to attend second time we have to give some message.
how we will write code in page_load.

you didn't tell where are you are storing the name of the attendees initially. Each time you load the page you need to check whether the name exists in the list amongst all the records. If the current entry matches with any of the record you pop a message saying that the user is logging in the second time. I hope this would help you in solving your problem.
Somethings seem HARD to do, until we know how to do them.

With a text editor. I find Visual Studio is best, but some people like Notepad.
Seriously, you have to determine who is logged in, then find out if they have taken the exam before. If they have you deny them access, otherwise you permit them to sit the exam.

Store the last attendee records and on form load search that username if datareader give record the show message...

Hi guyz, I know this's quite a mess but please just focus on the scopes and why some code parts out of the logical test blocks are skipped
private void listBox1_DragDrop(object sender, DragEventArgs e)
{
FileInfo fi;
string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);
int subX = 0;
for (int ctr = 0; ctr <= files.Length; ctr++)
{
if (!listBox1.Items.Contains(files[ctr]))
{
fi = new FileInfo(files[ctr]);
if (fi.Attributes.ToString().Contains("Directory"))
{
for (string[] subArFiles = Directory.GetFiles(files[ctr]); subX <= subArFiles.Length; subX++)
{
if(!listBox1.Items.Contains(subArFiles[subX]))
listBox1.Items.Add(subArFiles[subX]);
}
}
else
listBox1.Items.AddRange(files);
}
arFiles = (string[])listBox1.Items[ctr];
}
MessageBox.Show("hey!"); <big><font color=#ff0000></font></big>
listBox1.Items.Clear();
listBox1.Items.AddRange(arFiles);
lbl_msg.Text = listBox1.Items.Count.ToString() + " files were selected.";
}

Do you mean the compiler tells you that you can't reach the line of code indicated? Or you've run the program and it never reaches the line of code? If it is the latter what is the program doing instead, have you stepped through the code and watched what it was doing?

It's the latter. It might sound stupid but im not familiar with the compiler
can you kindly tell me how to do that??

Put a break point down at the start of the method - Thats where you click in the margin and a red dot appears.
Then run the code, when the method is entered the program will stop at the break point and you can then use Visual Studio to step through the code. F10 steps the program along one line. F11 steps the program into the method or property you are currently in.
The important things are that you can hover the mouse over an object and it will tell you want it is. There is also a watch window and a call stack which gives you useful information (You should find them at the bottom of visual studio)

It won't tell you, because it can reach the code. My guess would be an exception is thrown before it can reach the code. Probably because of this:
for (int ctr = 0; ctr <= files.Length; ctr++)
You should make that
for (int ctr = 0; ctr < files.Length; ctr++)
Indexation of your array begins at 0, not 1.
Standards are great! Everybody should have one!

Thanks
I had to surround the block with try catch to see what the error actually is!
Thanks for the tip Bekjong!
