The GC is the only thing specific to .NET that you need to worry about. The operating system, which you have no control as well, also dictates interrupts and schedules tasks based on thread priority. I would not design an RT system on a windows machine period unless I could accept a specific average and a large high time on response.
If you would give a better description of your RT system I would see if I can elaborate further if .NET can be applied, but no gaurantees.

Can I reference a strong-named assembly through the GUI? I tried to add it with "Add Reference", but this makes a local copy of my assembly. Should it do that? I thought putting them in the GAC eliminates this. thanx
|

Whatever is in the GAC should be in the .Net assemblies tab when adding a reference. But if you're working on the code for that strongly named assembly, it's fine to keep the project reference. When you build your installer, you can specify that you want the strongly named assemblies to go in the GAC and the rest of the assemblies to go into the install directory.

You have to install the strong named assembly in the assembly cashe. Then you still can reference it locally, however, if you delete it locally, your program will still work, because it will find it in the assembly cashe

thanx guys.. i found what the problem was: after adding it to the GAC i did a rebuild of the assembly, and i added a reference to it. but now the GAC had a different build version, so my program thought its a local one.

Hi All,
I have a little problem here...I know it might be easy, but I don't get it 
Situation:
A Form with a DataGrid bound to a Table. This Datagrid display all datarows...perfect.
Under the Datagrid is a butoon called "New". If I click on it, a new form comes up, where I enter a new datarow and write it into the database...works perfect, the data is in the DB.
But now, the last operation of the NEW_CLICK function should be, that the DataGrid of the calling form updates, so that the new record will be seen.....and that don't work! (
Has anybody please a code-sample which explains how this is done?
Thank in advance,
Iceman571

How are you refreshing your datagrid. Did you run through the code that binds the data again?

I've tried this, yes...but as you can imagine...it didn't work

What you can try to do is to refill your table. You are probably using the tableadapter to fill the datatable, and then you are using the datatable as the datasource to the grid. Well, if you refill your table using the adapter, it will get all the current values from the server, and sequentially display the new row in your grid.

Interesting...if I click a second time on my NEW Button, in the Background, the Grid gets updated...
Heres my new-click function:
private void btnSparteNew_Click(object sender, EventArgs e)
{
frmSpartenpflege f = new frmSpartenpflege();
f.Show();
this.tbl_spartenTableAdapter.Fill(this.spartenDataSet.tbl_sparten);
}
|
|
|
|
|
SOLVED!!
A stupid error...
I had to open the second from with "f.ShowDialog();"
Thanks for your help anyway...

Hello,
I am using Windows Installer Setup Project to deploy my application. However, two files are always created: Windows Installer Packeage (.MSI) and setup (.EXE). Is there a way so that only one file is created?
Thank you.

Oh yeah. I mean MSI
Sorry

Hi,
I have created a simple WinForm control (as a replacement of activex) in c#.net . I embedded it in my html page, it works fine.
Now i have created a delegate to handle a event "xyz". Now this "xyz" event is called on the "mouseclick" event of my control (actually its one of the compenent i.e. textbox).
In the class declaration.. <code>
public delegate void RecogniseCommandDelegate();
public event RecogniseCommandDelegate VoiceCommand;
....
.....
private void txtUserText_MouseClick(object sender, MouseEventArgs e)
{
VoiceCommand();
}
</code>
The problem now arises is how do i register this event handling in my html page, so that when "xyz" event is raised i perform some action on the web page????????? It could be using JScript or VBScript or ASP.NET or any thing, what i need is a working example of such senario..
If any body could help on this, i would really be greatfull.
Thanks in anticipation.
P.S. I used delegate because i couldnt figure out a way to diretly handle the mouseclick( or any other event for that matter) event. If any body can do it without delegate, that would be great too.

As far as performance issues are concerned I have a question ....
I have to make multiple selects based on date inside of a loop.
Is it wise to use the USING statement for the datareader inside of the loop or does something need to be done outside the loop.
Here is my current code.
<br />
using (SQLCommand selectAnnv = new SQLCommand(_database)) {<br />
SQLParameter paramDate = new SQLParameter("@DATE");<br />
<br />
selectAnnv.CommandText = "SELECT id FROM " + TMEMBERS + " WHERE registered = '(@DATE)'";<br />
selectAnnv.Parameters.Add(paramDate);<br />
<br />
<br />
<br />
for (DateTime anniversary = lastHandled.AddDays(1); anniversary <= now; anniversary = anniversary.AddDays(1)) {<br />
paramDate.Value = GStatic.GetISO8601(anniversary);<br />
<br />
using (SQLDataReader readerAnnv = selectAnnv.ExecuteReader()) {<br />
while (readerAnnv.Read())<br />
ids.Add(readerAnnv.GetInt32(0));<br />
}<br />
<br />
}<br />
<br />
}<br />
Should the bolded/italic part be decalered outside of the loop?
|
|
|
|
|
BTW this is just an example there is actually a few more variables to read so ExecuteScalar does not apply
|
|
|
|
|
Why not just use a date range in your sql statement?

The engine does not support date type
|
|
|
|

Could you clarify that statement for me? You're using a SQLDataReader, so you're talking to a SQL Server.

I'm sorry this is a custom DB much like SQLite, with even more limited types

The first approach is not actually saving "files in the database", it is only putting in a reference to the file on the disk. If you are going to ensure that the file remains on disk then this approach will work.
The second approach is the only one to actually store the file in the database. So it is the only one that meets your requirements as you have explained them.

Which you chose depends on a lot of variables that is applicable to your specific project. Here are some thoughts that you might consider
1) Are the paths accessible by other applications [web server?] that might need them
2) Do the files have different backup requirements then the database? Maybe you might have a dedicated file server backup
3) Are there lots of reads and modifications? If so you might consider storing just the path if the files are extremely large, as this is the purpose of the file system.
4) Do you have to jump through permissions hoop to synch the application accessibility to your database and file server
5) Is the database and file server on two different machines? If so and your database server is under heavy loads, you might consider offloading some of the work to the file server. In this case though you have to keep in mind you might run through networking issues.
and list goes on and on...
