Re: Sound level on sound card input alldates1-Aug-04 5:02 alldates 1-Aug-04 5:02  But how programs like SoundForge, Adobe Audition (CoolEdit) or any other audio programs show the level in db of the sound without any Microphone or calibration? > Someone asked this very same question about a month or two ago... I try to found in this board messages about this problem? but i found nothing. Many years ago i create such ptogram on pascal under dos. But now i need to write it on C# under Windows. I can't find any docs about this theme. Re: Sound level on sound card input Dave Kreskowiak1-Aug-04 16:51 Dave Kreskowiak 1-Aug-04 16:51  That's because you're under the impression that "decibel" is a measure of the loudness of a sound. It's not. It's a measure of relative signal strength. Those programs are showing you the decibel power of a small sample of a signal relative to itself, or the signal strength around the sample. There is absolutely no way a sound card can tell you what the decibel power of a sound is because it has no reference to compare it to. Don't bother searching for the answer to the previous question. It's the same as this one.

Let me know exactly what you are looking for and I might be able to help you out. But please, keep it in the forum instead of private e-Mails, as it may help others as well. Re: Help in Grid Control murali_utr2-Aug-04 5:03 murali_utr 2-Aug-04 5:03  hi, thanks for ur reply. in case of DataGrid is faced some problems in vb 6.0. so afraid about datagrid then only searching any other control. I don't know how this working on C#.Net. How u feel datagrid in ur project. it's ok to do? Have A Nice Day! Murali.M Re: Help in Grid Control DougW482-Aug-04 13:58 DougW48 2-Aug-04 13:58  The .Net datagrid seems to be very stable and easy to use. I wouldn't hesitate to include it in your form. The simplest method I have found for using the datagrid for this type of project is once you have an invoice or order ID, you bind your datagrid to a dataset with "items" that are being purchased. Each of these items has a column for Invoice/Order ID as well. I think if you use the datagrid, you'll be happy with your choice. For a project such as this, there are a few details you have to keep in mind, such as calculating line totals from the price and quantity. If you need help with things like this, just keep replying in this post, or start another one...I don't respond much, but I read the questions on codeproject almost every day! - D How to generate XML Documnets 31-Jul-04 11:23 31-Jul-04 11:23  Hello everybody Can anybody tell me how to generate Msn Messnager 6 or higher's chat log styled XML Decuments. Cheers take care byee Rizwan Ahmed Re: How to generate XML Documnets Heath Stewart31-Jul-04 15:02 Heath Stewart 31-Jul-04 15:02  Can you be a little more specific? Have you even read the .NET Framework SDK for the System.Xml[^] namespace, or are you just looking for someone to do the work for you. You won't find the latter here. This forum is for asking specific questions, not finding free help. Read the documentation for classes like the XmlTextWriter or the XmlDocument and, if you have questions, ask here.   Microsoft MVP, Visual C# My Articles Re: How to generate XML Documnets Salman Taseer`31-Jul-04 15:05 Salman Taseer` 31-Jul-04 15:05  thank you sir. actually i wanted a quick hellp coz i have never studied it nut want to use some where in my project. 1. for a little data base 2. dor genrating well formed documents. any wayz thnx for reply God bless byeeee Rizwan Ahmed Re: How to generate XML Documnets Heath Stewart31-Jul-04 15:10 Heath Stewart 31-Jul-04 15:10  There's plenty of articles here on CodeProject dealing with such topics - just search or browse the categories.

My application had to process an *.xml file through Excel COM. Cause of I use native Excel help for VBA : “VBAXL9.CHM” .But there is any troubles .When C# generate proxy for excel object it not consider about optional argument and cause of I should explicit pass this arguments every time in methods call. In many places into excel help referenced behavior of an methods with parameters by default (optional parameters which omit), but I don’t know what it are. Where I can learn about definition of this defaults parameters???? Re: VBA and C# Heath Stewart31-Jul-04 14:59 Heath Stewart 31-Jul-04 14:59  Use Missing.Value, or something like this for optional parameters: object missing = Missing.Value; excel.Save("filename.xls", ref missing, ref missing, ...); (Note: this is sample code; it won't compile) The help still applies. Since the RCW (Runtime Callable Wrapper) is generated over the typelib, the types and members are the same (may marshal a little differently; knowing comes from reading and experience). Read Interoperating with Unmanaged Code[^] in the .NET Framework SDK - especially the parts about COM interop and COM marshaling - for more information.   Microsoft MVP, Visual C# My Articles Re: VBA and C# Anonymous1-Aug-04 3:35 Anonymous 1-Aug-04 3:35  Thank Re: VBA and C# Dave Kreskowiak1-Aug-04 4:33 Dave Kreskowiak 1-Aug-04 4:33  And quit crossing posting in so many Forums.

RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome NetworkStream/TcpClient leppie31-Jul-04 6:14 leppie 31-Jul-04 6:14  Hi there all Has anyone experienced the NetworkStream gotten from the TcpClient underload conditions sends out packets in reverse!? I have done a low-level packet capture of my local port and it confirms what I see at the server. Packets that are queued , tend to get mixed up when the buffer is not full. Seems to send the packets while actually sorting them... any ideas? top secret xacc-ide 0.0.1 Re: NetworkStream/TcpClient Heath Stewart31-Jul-04 6:22 Heath Stewart 31-Jul-04 6:22  Set TcpClient.NoDelay to true (default is false). This disables coalescing of packets by sending them immediately instead of storing them until a significant amount of data can be sent. This results in a more chatty protocol, but should eliminate the problems you're having.   Microsoft MVP, Visual C# My Articles Re: NetworkStream/TcpClient leppie31-Jul-04 6:28 leppie 31-Jul-04 6:28  Heath Stewart wrote: TcpClient.NoDelay to true Tried that, and every property I have access too, still the same... top secret xacc-ide 0.0.1 Re: NetworkStream/TcpClient leppie31-Jul-04 6:33 leppie 31-Jul-04 6:33  Other things I have tried (but same results): - Send ever packet via a threadpool It only happens when the NetworkStream is buffering (when doing Write in "quick" (still by hand!) succession). Its not the server either, this has been verified by the captured packets, and the fact that an unmamaged client behaves correctly in the same scenario. top secret xacc-ide 0.0.1 Re: NetworkStream/TcpClient Heath Stewart31-Jul-04 15:12 Heath Stewart 31-Jul-04 15:12  Out of curiosity (sorry, no clue what might be wrong without digging into lots of IL (and a lot is actually internal implementation in the CLR - I always hate that road block)), why would you try to solve this in a ThreadPool? I would expect that to make it worse (nothing says your queued work items are executed in order).   Microsoft MVP, Visual C# My Articles Re: NetworkStream/TcpClient leppie31-Jul-04 21:53 leppie 31-Jul-04 21:53  My initial idea, although I dont think it works like I thought ( ) was to just get a little pause or something, tried some locks too. Basically I place a Console.Write after the NetworkStream.Write , so I can see it IS being dispatched by me, in a sequencial order, which I have confirmed. Here is a trimmed version of a packet "dispatch" leaving my port, as captured, by NGSniff and WinPCap, each line refers to a stream.Write action, where the id is generated sequencially, and the data is just entered on the keyboard. This refers to a single packet leaving my network port. id="msg135" 7 id="msg134" 6 id="msg136" 8 id="msg137" 9 In this case, the order seems random, most other cases the order seems to be in reverse, that would look like: id="msg137" 9 id="msg136" 8 id="msg135" 7 id="msg134" 6 This can surely not be the real behaviour of the NetworkStream, as for a workaround I would have to add an unessary packet layer that should already be provided on a lower OSI level. Thanks for trying to help though top secret xacc-ide 0.0.1 refreshing .dlls after compilation Cristoff31-Jul-04 2:19 Cristoff 31-Jul-04 2:19  I'm developing components in separate .dlls. Unfortunately I have to manually delete the compiled .dlls so that they are refreshed in the main project each time I change them? Is there any other way (automatic)? It is the same story with the resources but I know it is an issue with VS.NET. It is quite annoying each time I change a resource I have to remove it and then add it again. Re: refreshing .dlls after compilation Heath Stewart31-Jul-04 4:52 Heath Stewart 31-Jul-04 4:52  Remove the assembly references. Right-click on the project that depends on those assemblies, select Add Reference. Click the Project tab and add the projects in your solution that your current project depends on. Now a build dependency is established so that any changes in a dependent project (or their dependents, etc.) will force a recompile and - if necessary - will copy the newly built assembly into the target path for the project that depends on it. This also makes sure that the versions are never incorrect, though you really shouldn't use automatic versioning in larger solutions because versions in .NET are important (they are part of what defines a Type - a difference only in version results in different Types). If you read the Visual Studio product documentation - or even just explore the IDE - you can find a lot more useful tips.   Microsoft MVP, Visual C# My Articles Re: refreshing .dlls after compilation Cristoff31-Jul-04 19:12 Cristoff 31-Jul-04 19:12  Well, all my projects are in the same solution from the start but most of the time, when I change any of the .dlls the newer versions are not copied in the .exe folder. Most of the time this happens only if I delete the bin folder and execute Build twice. I have thought about outputting the compiled .dll directly in the main projects bin folder but I haven't tried it yet. there should be a more logical solution. Re: refreshing .dlls after compilation Heath Stewart31-Jul-04 19:14 Heath Stewart 31-Jul-04 19:14  Cristoff wrote: there should be a more logical solution There is: as I said, reference your projects in a solution using the Projects tab - not the .NET tab. Trust me - I managed a solution of well over 60 projects as the senior software architect and build master for a very large, N-tier .NET application using VS.NET. This will set up build dependencies and will update your dependent assemblies for a project that references them (directly and indirectly) in the target path (bin\Debug, bin\Release, etc.). And also as I said before, this is documented in the Visual Studio product documentation.   Microsoft MVP, Visual C# My Articles
