Create a FileStream.
Create a StreamWriter that uses the FileStream object.
Write the Text to the file.
Close the StreamWriter and the FileStream.

If you want the data to be read from the db, then you have to connect.
What I think you should be doing is having a data access layer, beneath the businses object you are displaying. If you are displaying a 'person', you would have a person data object. When you have data to save, get the front end / business layer to write the changes to the data layer. This layer should have a 'Save() / Write() / Commit()' method, which you can call when you need to, which will commits the data to the database. This way, the data layer is always in sync with the DB (Assuming nothing else writes to the DB), and you shouldn't need to read from it, only when first loading the object.

Hello all,
I have a c# project in wich I need to display some barcodes. In the past, I've used an Code128 font from http://grandzebu.net/informatique/codbar-en/code128.htm[^]in some c++ projects, and had no problems printing the codes (using gdi).
Now, in the c# project, it uses gdi+ and it seems that it has some problems with some fonts (the code128 included), and always replaces it with Arial.
After searching the net and trying some proposed solutions, I gave up on trying to make gdi+ use the font, so my questions are:
1) Is there any way to convert the font into a format that gdi+ can swallow? (preferably a free one, this is a kind of pet project)
2) Any way of using c++ to draw only the barcode using gdi on the same page that the rest of the program will display the rest of the print output?
TIA

Hi
I have 2 listboxes on my form and in the form load event I want to get values from specified registry keys to appear as items in to each listbox. The first listbox works fine using this code:
RegistryKey key1 = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\RegKey_test");
if (key1.GetValue("MultiString1") != null)
{
ListBox1.Items.Clear();
string[] items = (string[])key1.GetValue("MultiString1");
for (int i = 0; i < items.Length; i++)
{
ListBox1.Items.Add(key1.GetValue("MultiString1", items[i]));
}
}
But for the second listbox I have practically the exact same code (But with a different registry value name and listbox). However, when the form loads ListBox1 shows the correct values but ListBox2 shows 'String[]Array' for each number of multistring values. Here is my code for getting the values from "MultiString2" into ListBox2:
RegistryKey key2 = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\RegKey_test");
if (key2.GetValue("MultiString2") != null)
{
ListBox2.Items.Clear();
string[] items = (string[])key2.GetValue("MultiString2");
for (int i = 0; i < items.Length; i++)
{
ListBox2.Items.Add(key2.GetValue("MultiString2", items[i]));
}
}
Why do I have this error when both sections of code are not that different? Can anyone advise me please?

I have tried changing ListBox2.Items.Add(key2.GetValue("MultiString2", items[i]));
to
ListBox2.Items.Add(key2.GetValue("MultiString2", items[i].ToString));
But the same problem occurs. All registry key and value names are correct.
Stepping through the code I can see that the value for ListBox1.Items is {System.Windows.Forms.ListBox.ObjectCollection}
Should the listbox items be an ObjectCollection?

You already got the list from the registry in the first line, then you go and get the list again, and again, and again, and again, and again, for each and every pass through this loop. There's no need to do that. You already have the list in a string array you chose to ignore.
string[] items = (string[])key2.GetValue("MultiString2");
for (int i = 0; i < items.Length; i++)
{
ListBox2.Items.Add(items[i]);
}

Hi all,
I have an urgent question.
I am writing an windows service to retrieve files from a network drive mapped as Y: I get the following error... Could not find a part of the path "Y:\verify".
When I run an Application it works fine, so I tried to shell the exe from my service, but still get the error!
I have read and tried several things but to no success 
Can anyone please assist me?

The network drive is mapped to a particular user (yours I presume). It is highly unlikely that you are using your user for the service, so it won't be able to see the mapping because this is not present for the user. Your choices are:
1. Rewrite your code to use the UNC path.
2. Change the user of the service to your user.
3. Add the mapping to the user that the service runs against.
Option 1 is your best option (oh, and don't hardcode the value - pick it up from a config file so that you can change it later on.)

Thanx for the quick reply 
If I use Option 1, the share uses Authentication. It's basically a DMZ share...
How can I then authenticate the service?
If I use Option 2, I have tried to set the Log On of the service to my domain logon, thought it would then see my mapped drive???
Under which ServiceAccount type should I install the service?
Any advice here?
|

This is most likely because your service is running under the local account. A local account is just that - local. You can either configure the service to run with a specific user's credentials (I've done this and it works) or use a UNC path (I haven't tried this, so I don't know).

Hi thanx for the reply!
I ran the service using my domain login, I thought that this will allow the service to see MY mapped drives. But still got the same error.
Under which ServiceAccount should I then install,localService, Network Service?
Please assist this is of great importance

Mapping drives is so '80s; use a UNC.
|

the '80s were great, so mapping drives also

Mapping isnt so 80's when having to interface with DOS

hi all,
i use ShowWindow(hWnd, SW_HIDE); in order to hide a running windows application.
it works good. and hide any application i want. (for example notepad)
(after calling that fuction the app is not seen in taskbar any more but available in task manager - still running in background)
the problem is:
i cant bring that process back with using ShowWindow(hWnd, SW_RESTORE);
what should i do in order to bring the hidden process back to the foreground ?
any ideas ?
thanks in advance.

Try ShowWindow(hWnd, SW_SHOW); instead.

The problem that you have here is that MainWindowHandle is 0 because the window is hidden. To get round this, save the window handle that you used to hide it and pass that into ShowWindow instead of the MainWindowHandle.
