What do I remodel in my application configuration
Do I work on the connections for
<br />
<connectionStrings><addname=<br />
"MyProgram.My.MySettings.NWConnectionString"<br />
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;<br />
Data Source=|DataDirectory|\DataConnections\NW.mdb providerName="System.Data.OleDb" /></connectionStrings><br />
Thanks Dave

So long as your app.config has a <connectionStrings> section, something like:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="MyAccessDBConnectionString"
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=...."
providerName="System.Data.OleDb" />
</connectionStrings>
</configuration>
In your code, the connection string name would be, in this example obviously, MyAccessDBConnectionString.

hi to all
i had made an application for which no dlls is required and hence it can be runned by just copying the .exe file to the other PC. now when i try to copy the EXE file to network drives and run it from my pc it is running successfully, but when i go to another pc and run the exe file which is in network drive it is throws an error saying
"application encountered a problem,Please tell microsoft about this problem.and two buttons 'send report', 'dont send' "
my intension is to keep the exe file in the common network and distribute the shortcut of that exe files to every one, who wants to use the application.so that updation for the exe file(if occurs) can be done very easily to that exe file in network,and it will be automatically reflects to every one as all are using shortcuts. this is very clearly done by VB 6.0 and it is not able to done by VB.net.For this simple reason our company is avoiding VB.NET.
please do the need full.
Thanks & Regards

Go to MSDN and search for "Code Access Security". Any managed code running from a non-local, i.e.: network share, source is, by default, not trusted. Your application is run in a heavily restricted sandbox that has very limited permissions to system resources. Kind of like trying to your your app in a web brwoser with the securty turned up.

Hi,
I was wondering if anyone of you would know how to eliminate the SAVE AS dialog box. I need to create a script that will automaticaly save file as MDI (or PDF). The name of the file will be provided as parameter to the script. Any help will be great.
Thanks,
Flavio

What "Save As" dialog?? What script?? What is this script supposed to do?? You're going to have to supply a lot more information about what you're doing. There isn't enough detail in what you've posted for anyone to help you.

Hi,
Here is the situation. I have a C++ code that generate reports and send them to the default printer. Now what I would like to do is instead of sending to print I would like to generate the report as either MDI or PDF. As you know, when you try to print to MDI printer it ask you for the name and file location(the standard Windows Save As dialog box). I have hundreds of reports to be created and I dont want to enter the name for each one of them. I would like to automatically save all the reports as MDI. The idea is to create a loop and call the VB scrip within my C++ program passing the file name as parameter.
I hope this helps explan better my situation. If not, feel free to let me know.
Thanks a lot.
Flavio

Ahh! It's not going to work. There's no way to get rid of the Save As dialog in the print dialog because there is no way to set the filename of the printed document.

I want to see if it is possible to change a font color of one row of a datagrid given a certain value is in the row. Is this possible? How?
|
|
|
|
|
For the .NET 1.0 and 1.1 DataGrid, see this FAQ[^]. There's a bunch of tidbits on using the DataGrid.
Or were you talking about the DataGridView in .NET 2.0??

Using Visual Studio (2005, 2008, maybe 2003):
Short answer (quick):
Build > Publish <project name="">
Long answer (thorough):
Solution Explorer > My Project > Publish (it's a tab) > enter paramaters > Publish now.
If your VS is not recently updated, you will not be able to do this. You must get the newest version (I use SP1).

I am using a Component C1DateEdit. I commonUpDownButtonClick and a CommonValueChanged Handles on all of those controls. After either UpDownButtonClick or CommonValueChanged is executed it calls another routine that figures out which C1DateEdit was the sender if it was datDischargeDate then it calls sAbleDischargeReason().
Private Sub sAbleDischargeReason()
Dim bStatus As Boolean
If IsDBNull(datDischargeDate.Value) And datDischargeDate.Text = String.Empty Then
bStatus = False
Else
bStatus = True
End If
lblDischargeReasonNum.Enabled = bStatus
cboDischargeReasonNum.Enabled = bStatus
End Sub
The problem that I am having is that when it hits the if in sAbleDischargeReason() it is always true because this code is being executed before the value is in either datDischargeDate.Value or datDischargeDate.Text
I am not sure how to make this execute after the value is already there.
Any help is much appreciated.
Thank you

That's going to be a question for Component1's website. That's a functionality issue with their controls. ComponentOne site[^]

Is there not something I can do with pre or post validation. I have not used them but that seems like it could some how work.

Again, that's exposed entirely by the control in question. Validation could work, but how you have to do it is dictated by whoever wrote the control.

Thank you,
sorry if I have wasted your time.

It's not my time that's wasted. Most people who answer questions regularly here have never used ComponentOne controls. The base of experience on any one third-party control is going to be very low. The best source of information, and the great knowledge base, is going to be the support forums of the manufacturer of the controls.

I'm doing a project in VB.Net 2003 (I don't think the method and code would really change in Vb.Net 2005) and the client wants to be able to change the database location at any place on his computer. In VB.Net 2003, I'm using the data adapters with datasets, along with a connexion, but my problem is how can I connect the controls to the database and manipulate the data if the location is changed? It's all done with a few lines of code only. Should I forget this method and do it all in code, or maybe someone have a better solution for my problem?
Thanks!

You connect to the database using a connection string. You can change that string to look for the database in just about any location you want.
|
|
|
|
|
By changing only the connection string, the datasource of my grids will still be ok? I won't even need to change it? Well, thanks a lot!

I have a very weird problem. I'll try to be specific, but I'm just beginning VB.NET programming.
I built a SQL Server 2005 database from the ground up. Currently I'm building a front-end in VB.NET. I'm using a Janus GridEX 2 to make a hierarchy of projects, assemblies, and parts. For some reason, the projects and assemblies update fine, but the parts and "Assemblies to Assemblies" (used to make nearly infinate levels of hierarchy) tables create an error saying it can't update the Id. The Id is required to make the program work, so I can't just remove it.
The first two lines work. The last two do not.
Me.ProjectTableAdapter.Update(Me.ProjPurch2005DataSet.Project)<br />
Me.AssemblyTableAdapter.Update(Me.ProjPurch2005DataSet._Assembly)<br />
Me.Assy2AssyTableAdapter.Update(Me.ProjPurch2005DataSet.Assy2Assy)<br />
Me.PurchaseTableAdapter.Update(Me.ProjPurch2005DataSet.Purchase)
Is there a blatent reason that I'm just not seeing?

`Drew wrote: create an error saying it can't update the Id.
The Data and Table adapter require that the table's they are working on have primary keys. If your table doesn't have one, you can't do any updating of the tables until you put one in and update the DataAdpter or TableAdapter SQL statements to return that key field in the query results.
...or did I miss something in your post??
