Hi to all,
I am working on academic project. I require some help, please help me any one who knows the answer for following:
In my college 20 systems are connected with home network. Where we have a share(every system can access this space) drive. Now I developed a professor details interface.
This professor details is placed at shared location. So that any student can access this information from any system.
How can write such kind of application(using windows based C# application).
Please if you have any links related this share me.
Thanks In advance..To invent something, you need a mountain of junk in your mind.

It's Easy.
If your application is using Database. You can use SQL Server or Oracle.If you can think then I Can.

Thanks for quick reply,
Data base point of view ok. I will use SQLServer.
i want to know,how to access access user interface. How to create shortcut on each desktop. So that my application should located in shared drive and access to every one.To invent something, you need a mountain of junk in your mind.

You have a lot of question.
You can use MSaccess database but it's not friendly for MULTIUSER infrastructure. and you can connect server and other machines by using connection string.If you can think then I Can.

Exactly the same way that you create any shortcut; the link will point to the app on the share rather than on the local disk.txtspeak is the realm of 9 year old children, not developers. Christian Graus

i want to validate first if the form is already loaded or not.
if it is already loaded the form will just prompt it again perform it windows state to normal and focus but does not duplicate the form..
<br />
<br />
<br />
private void newToolStripMenuItem_Click(object sender, EventArgs e)<br />
{<br />
<br />
<br />
if (IsFormLoaded("form2"))<br />
{<br />
return;<br />
}<br />
<br />
<br />
Form1 frmshow = new Form1(); <br />
frmshow.MdiParent = this;<br />
frmshow.Show();<br />
<br />
}<br />
<br />
private bool IsFormLoaded(string formName)<br />
{<br />
bool Load = false;<br />
<br />
for (int i = 0; i < (this.OwnedForms.Length) - 1; i++)<br />
{<br />
<br />
if (this.OwnedForms[i].Name.ToString().TrimStart() == "formName")<br />
{<br />
this.OwnedForms[i].WindowState = FormWindowState.Normal;<br />
this.OwnedForms[i].Focus();<br />
Load = true;<br />
}<br />
<br />
}<br />
<br />
return Load;<br />
}<br />
<br />
<br />
<br />

why are you using hardcoded form name
if (this.OwnedForms[i].Name.ToString().TrimStart() == "formName")
"formName" should be formNameLife's Like a mirror. Smile at it & it smiles back at you.- P Pligrim

Hi,
I had a setup (of plugin of IE) (named Setup1) build in vs2005. Earlier If I used to install this setup on other PC's which doesn't have vs2005 and has only .Net framework2.0, the setup gets successfully installed.
After few days, I had installed vs2008 in my PC. After that, I had took the code of Setup1, rebuilt the dll, made a setup (named Setup2) using vs2005.
The main thing is, I had observed one thing, the new setup (i.e., Setup2) gets successfully installed on developing machines, but it gives the following installation error on the machines which does not have vistualstudio, eventhough, .Netframework2.0 and windowsinstaller3.1 is present. The error is:
Exception occured while initializing the installation:
System.IO.FileLoadException: could not load file or assembly 'Microsoft.mshtml.dll, Version=7.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. StrongName validation failed. (Exception from HRESULT:0x8013141A).
But on the same, Setup1 gets succesfully installed. But setup2 gives this installation Error.
If I run vs_piaredist.exe first and then run the Setup2, Setup2 also gets successfully installed.
Why is this happening with Setup2? why doesn't this happen with Setup1?

In my case it was because I referenced different "Microsoft.mshtml.dll" files (same file size, but different content). look at the Reference "Microsoft.mshtml.dll" , "Properties", "Path" field.

Dear All:
I am a bit confused about the delegate with a returned value.
For example, I have a delegate as:
public delegate int Adelegate(MyClass instance)
Like this, what happens to the returned value if I use multi delegate please?
Further, if the delegate returns a bool, how can I declare a delegate that output a bool value please?
Should I declare it in the parameters or the return value?
ThanksAsura

That would depend on what it's doing and what you expect it to do!
Or were we just supposed to read your mind?

|

|

So you modified your post and we are still supposed to guess what is not working and what you expect it do?Why is common sense not common?

Off the top of my head, I'd guess you're missing a break; statement after setting FormLoaded to true.

You Should First Compile it and Send the error message IF generate. Else Debug it Line By Line.

There are many ways to achieve a single instance form, and I suspect that the problem you are having is that the form name you are searching for doesn't exist in the OwnedForms collection."WPF has many lovers.

It looks like you might be missing a form in your loop.

Hi,
I developed a simple application with C#, using the VSTO 2008 tools.
It is supposed to be used a mass-mailing item from Outlook 2007.
All it does is taking the mail recipients from the "To", "CC" & "BCC" and filter out the addresses which are either invalid or marked as non-subscribers. (There is a DB which stores all the email addresses)
The problem is not the logic inside, it works fine.
When the method is complete, the outlook starts to go crazy:
The icons at the bottom system tray flickers, CPU soars to 100% and the mail is stuck in the outbox.
Sometimes I can see the "Outlook is synchronizing folders".
Has anyone got the clue why is it happening?
I am attaching some of my code:
namespace SMOutlook2007AddIn
{
public partial class ThisAddIn
{
private Outlook.Application App = new Outlook.Application();
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
if (string.IsNullOrEmpty(ACCOUNT_NAME))
{
MessageBox.Show("Couldn't Load SM Addin.\n No ACCOUNT_NAME in config file.");
}
else

{
throw new System.Exception("Unknown Recipient Type " + addressEntry.DisplayType + "\nRecipient Name: " + addressEntry.Name);
}
if (addressEntry.Members == null || addressEntry.Members.Count == 0)
{
return new string[0];

List<string> addresses = new List<string>();
foreach (AddressEntry entry in addressEntry.Members)
{
addresses.AddRange(GetEmailsList(entry));
}
return addresses;
}

{
if (Emails == null || Emails.Count == 0)

Do you know that your message contains 4.3479162 KiloMeters of characters?
And that it is unformated => hard to read?
|
|
|
|
|
unformatted ==> ignored.
|
|
|
|

To expand on what Luc said,
A ton of code and unformmated = ignored.Why is common sense not common?
