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. Big Grin | :-D

Hell, that's exactly the thing I'd like to do Big Grin | :-D

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 Laugh | :laugh:

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.. Unsure | :~

InterOp C++ library

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.

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 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...

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.

The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached from connecting from DotNetNuke to SQl Server 2000.

Treeview deselecting nodes?

PhrankBooth20-Sep-05 4:16

20-Sep-05 4:16

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 />
//*********************************<br />
bool isChecked = false; //it will clear the check, true will set the check<br />
foreach(TreeNode node in treeView.Nodes) <br />
{<br />
setCheck(node, false);<br />
}<br />
//**********************************

Hope it helps.

Problems with Sockets

Glenn Inman19-Sep-05 5:22

Glenn Inman

19-Sep-05 5:22

I am working with Sockets – I find this interesting, and I would call it a bug. It seems odd that the bytes that comes from GetAddressBytes is not valid for creating a new address given the prototype for it is the same. (A System.ArgumentException is thrown) let me know if you find this odd, a bug or if I am just not understanding how to use this interface correctly.

using System;
using System.Net;
using System.Net.Sockets;
using System.Windows.Forms;
using ThreadingEx;

namespace foo
{

[STAThread]
static void Main(string[] args)
{
IPHostEntry Host;
IPAddress Address;
IPAddress Address2;

Host = Dns.Resolve(“AnyAddressThatResolves.com”);
Address = Host.AddressList[0];

/*
** This will cause an error, the prototype is
** public IPAddress(byte[] address);
** and the GetAddressBytes is
** public byte[] GetAddressBytes();
*/
Address2 = new IPAddress(Address.GetAddressBytes());

}

}

I am using System.Management.Managementobjectsearcher in C# to read processor Number. Internally it uses COM objects.

So it gives error that System.Runtime.Interopservices.COMException and error message is Com object is not registerd.

This error comes only in windows98. It works well with 2000,xp,2003 etc...

So tell me how to solve this error..
