Hi,
I am working on an application that can run both remotly or locally.
The Listener is publishing 3 objects using .NET remoting. The Client has only the UI, all the calls to the database and the reporting are done through the Listener.
The remote computer that hosts the listener is also hosting the Crystal Report, .rpt, files.
The Client has also a Crystal Viewer. When the user clicks on a button, the Client sends the request along with an ID to the Listener that upon the ID provided selects a .rpt file from the server's disk, loads the file into a CrystalDecisions.CrystalReports.Engine.ReportDocument object, sets the parameters to that report (datasource, user/pass) and returns it to the client. The Client receives the object, binds it to the viewer and displays it. At least that is what is supposed to do...
Now if I set my application to run locally, without the listener, but using the same code, same objects, to load the .rpt file, everything works fine. The moment I set it up to work remotly, the system stops at the Load() method (the bold line).
It does not throw me any exception, it just stays there forever 
<br />
...<br />
ReportDocument oRptDoc = new ReportDocument();<br />
<br />
string sFullPath = "test.rpt";<br />
<br />
oRptDoc.Load(sFullPath);<br />
<br />
CrystalDecisions.Shared.TableLogOnInfo crLogonInfo;<br />
crLogonInfo = oRptDoc.Database.Tables[0].LogOnInfo;<br />
<br />
string sDataBaseName = "my database";<br />
string sServerName = "my server";<br />
string sUser = "my user";<br />
string sPassword = "my password";<br />
<br />
crLogonInfo.ConnectionInfo.ServerName = sServerName;<br />
crLogonInfo.ConnectionInfo.UserID = sUser.ToUpper();<br />
crLogonInfo.ConnectionInfo.Password = sPassword.ToUpper();<br />
crLogonInfo.ConnectionInfo.DatabaseName = sDataBaseName;<br />
<br />
oRptDoc.Database.Tables[0].ApplyLogOnInfo(crLogonInfo);<br />
<br />
return oRptDoc;<br />
<br />
I hope somebody has any ideea...
Thank you,
Virgil

Is there anything in VS or an addon that will allow me to print out the entire project in one click. I used to work in VB6 and there was a program called starprint that would do that. i could probably write my own, but i am looking for something already done.

No such tricks available. Better you could write one and submit to CP.

I'm working on a project written in C# / ASP.NET, and we're using crystal reports for em..reports. We're now in trouble, because our database is designed in a way that several companies can work on it at the same time, and the application is too.. our problem are reports, because most of them have a company logo in the top right corner and..it would be bad to show the same logo for ten different companies.
Any ideas how to deal with this?? Is there a way to put a link to an image dynamically? It would be terrible if we were to create a new report for each new company..
I'm not sure if I've explained this well enough.. Any ideas are welcome..

As per my knowledge there is no such techinics which will load report image dynamically based on some condition.
In case, if you want to show different the company logo's, you can store respective logos in some table. Once that is done then try to bind that feild which contain image to your report based on some company specific values.

Hell, that's exactly the thing I'd like to do OR, I can kill the man who thought of placing the logo on reports. Blast it. If need be, I'll go to work armed ask for a specific name, but the root of this problem will come to light 
Darn.. I guess we'll dump the logo in the end or something.. But I still keep thinking that there must be a way of doing just that..

Maybe this is a stupid question, nevertheless, is it possible to interface a C++ class library in C#.
Some good reasons do this:
1. There are literally thousands (millions?) of C++ class libraries around in cyberspace, it seems a terrible waste not to able to use them.
2. I still believe that good conventionally written number crunching C++ code is (far) more efficient than C# / .NET code (e.g. arbitrary precision DSP).
3. C# / .NET code is (of course) much more suitable to write Windows / UI code. Combining the two should work out just great.
InterOp is possible with plain C DLL's and many articles are available to this subject. Is there anybody out there who encountered the same problem and has some suggestions.

Yes, there are a number of options
1. Managed C++, just write a wrapper and call that from .NET
2. COM - wrap your library in COM and then use COM interop
3. If your library is a dll, use PInvoke and just call it directly.
I believe there's an article around on using C++ libs in C#, I'd be surprised if the solution was not one of the above.

NCache boosts .NET application performance through in-memory clustered object caching. NCache not only lets you cache read-only data but also complex transactional data with relationships. NCache provides a graphical tool for configuring and monitoring clustered caches from a single computer.
NCache provides the following features:
1. Single-server or clustered server-farm configurations
2. Fully supports ASP.NET 2.0 Cache API
3. Read-through, write-through, and write-behind operations
4. Object relationship handling through intelligent dependency management
5. Cache clustering as Replicated Cache, Partitioned Cache, or Near Cache
NCache also includes a Clustered Session State for ASP.NET that lets you use sessions in server-farms without fearing single-point of failure and slow performance of Microsoft’s ASP.NET Persistent Session State.

Thanks - I've added this to the list of companies to cheap to pay for advertising and therefore unlikely to offer good support, and certainly not worthy of my financial support.

Have you tried to search some free/opensource SIP libs? I hope there is something...
However, you have to read and understand the SIP specs ().

I understand the SIP and VoIP...
I need help developing the SIP Client using C# for win platform...
SO, i tried searching samples or ideas around .....but i couldn;t find anything promising....

I think that once you have familiarity with the SIP protocols, the hard piece of work is to capture the sound and incapsulate it on one side, on the other side you have to playback the received sound...
Regarding capture/playback there are some good articles in CodeProjects: perform a little search. I believe there is some kind of library including all necessary tools to record and playback waveform files.
Personally I don't know much about VoIP, but I strongly suggest you to find some library, because implementing a complete High-level protocol (such as SIP) could require months of work, especially the audio codecs implementation!
Even a *simple* protocol such as POP3, isn't so much simple to implement...
Tozzi is right: Gaia is getting rid of us.
Do you feel the way you hate or do you hate the way you feel?

Hi,
I have some positive experiences with SIP and VoIP and I wish to give you an advice. If you need to learn about SIP you can start here: http://voip-sip-sdk.com/[^] They provide many sample programs and you can try them for free.
For me it was a good start to learn more about SIP.

I take it there's a question buried in this post somewhere? Perhaps a code snippet of what your having a problem with will help too.

Hello,
I'm using a treeview and I have selected several nodes.
Now I'd like to clear those node selections so that there are no nodes selected in the treeview.
The only way I've found to do this is to reload the treeview with the object, which sets it back to original state. But there's got to be a better way.
Anyone have any ideas?
Thanks in advance,
--PhB

As far as I know, a treeview can only have one selected node, which you can retrieve with the SelectedNode property.
Therefore, I'm not sure what are you refering to when you say that you have selected *several* nodes - maybe checked, like if the treeview is set to diplay checkboxes, and you refer to the checked nodes?
Anyways, if you want to "deselect" the one and only node that could be selected in a treeview, try setting the SelectedNode property to null.
Otherwise, if you want to "uncheck" any checked node, you must navigate the nodes, say recursively, and set the Checked property of each node to false.
Assuming you have a treeview named treeView in your form, create a method called setCheck and call it from wherever you want to perform the clearing of checked nodes (or checking them for that matter):
<br />
private void setCheck(TreeNode node, bool isChecked) <br />
{<br />
if(node != null) <br />
{<br />
node.Checked = isChecked;<br />
foreach(TreeNode child in node.Nodes) <br />
{<br />
setCheck(child, isChecked);<br />
}<br />
}<br />
}
Call this method like this:
<br />
bool isChecked = false;
foreach(TreeNode node in treeView.Nodes) <br />
{<br />
setCheck(node, false);<br />
}<br />
Hope it helps.
