Re: Using Type and ConstructorInfo: Can't understand why this doesn't work... Luc Pattyn3-Jan-09 4:28 Luc Pattyn 3-Jan-09 4:28  Hi, as the exception says, you have a null reference; there is only one reference on that line, so t is null. reason seems to be you did not specify the full type name in the line above. MSDN on Type.GetType() says "typeName can be the type name qualified by its namespace or an assembly-qualified name that includes an assembly name specification."

Charith Jayasundara3-Jan-09 4:08 Charith Jayasundara 3-Jan-09 4:08  Hi, Can you please give me a practical example to distingish below two methods.. Method 1 string.Format("something","Something"); Method 2 string.Format(CultureInfo.CurrentCulture,"something","Something"); Thanks! Charith Jayasundara Re: Question on string.Format(...) Colin Angus Mackay3-Jan-09 5:21 Colin Angus Mackay 3-Jan-09 5:21  Your first example simply calls your second example but with null as the first parameter. The second example exlicitly uses the current culture to render the formatting. In other words, if you ask it to format a number it will place the delimiters and decimal markers in the correct place and with the correct characters. For example, if your culuture is set to EN-GB then 1.234 will be rendered, whereas if your culture is NL-NL the same number would be rendered as 1,234 The .NET documentation has extesive examples of how to use Format and on formatting in general, that should be your starting point.

Because some people like consistency and will set all parameters explicitly all the time. Other than that, I don't think it makes any difference for strings.

Charith Jayasundara Autoincrement ID field in a xsd tharkaway3-Jan-09 2:50 tharkaway 3-Jan-09 2:50  I have a table defined in a xsd that has an autoincrementing field that is used as the key to the table. The application uses ReadXML and WriteXML function to persists the dataset to an XML file. I am curious as to where the next value to use for the autoincrement field is persisted. I would have expected that when creating a new row in the table, the value for the ID field would be one greater than the highest value found in the table after the dataset is read in. It seems however to persist the highest value used in the past, even if those records have been deleted. In my application, when I create a new row, the ID field contains a 6071 when the highest value used before creating a new row was 5995. It does not appear that the autoincrement seed value is stored in the XML file itself, but where else would it be. How to check whether network busy or not? George_George3-Jan-09 1:20 George_George 3-Jan-09 1:20  Hello everyone, I am writing a backend program which will upload some big files to another server and I want to detect whether current machine's network is busy or not (I want to use relative non-busy time of current machine to upload files, as I do not want to impact other network related task on the machine as the upload file task priority is low). Does anyone have any idea about how to check whether current machine is busy with network I/O? Should I check some performance counters? thanks in advance, George Re: How to check whether network busy or not? Abhijit Jana3-Jan-09 1:34 Abhijit Jana 3-Jan-09 1:34  George_George wrote: Does anyone have any idea about how to check whether current machine is busy with network I/O? You can try it with WMI . I think WMI will helps you out. cheers, Abhijit Re: How to check whether network busy or not? George_George3-Jan-09 1:55 George_George 3-Jan-09 1:55  Thanks Abhijit, Do you have more detailed advice? Which API from WMI should I use? regards, George Re: How to check whether network busy or not? Abhijit Jana3-Jan-09 2:25 Abhijit Jana 3-Jan-09 2:25  I think You can Download "WMICodeCreator" , and can explore it. cheers, Abhijit Re: How to check whether network busy or not? George_George3-Jan-09 21:25 George_George 3-Jan-09 21:25  Thanks Abhijit, I have downloaded the WMICodeCreator. But it is just a tool to list all WMI classes. There are a couple of network and network adapter related classes/properties. Which one should I use? regards, George Re: How to check whether network busy or not? Abhijit Jana4-Jan-09 0:51 Abhijit Jana 4-Jan-09 0:51  When you will select the classes, you will get corresponding properties that are available. And will get the code in right pane, Change the language to C# from Tool. BTW: Check Senthil post also. cheers, Abhijit Re: How to check whether network busy or not? George_George4-Jan-09 22:30 George_George 4-Jan-09 22:30  Thanks Abhijit, I noticed a lot of similar ones related to network and network adapter.

Ref1[^] Ref2[^] cheers, Abhijit SQL or MySQL with c# Abdul Rahman Hamidy3-Jan-09 1:03 Abdul Rahman Hamidy 3-Jan-09 1:03  Dear All, I have developed many database applications with vb6,vb.net,c# as front end and SQL SERVER and MySQL as Back End. In truth i checked different tables and views in both SQL SERVER and MYSQL. I got better performance (fast) in SQL SERVER (my own check in a view which had 10000 records). I search alot and find out different ideas about them. I found in some website that MySQL is faster than SQL SERVER while in other i found that SQL SERVER is faster in performance than MySQL. In fact i dont know, now the question is what to use with c#, MySQL or SQL SERVER? if MYSQL than which Engine? Abdul Rahaman Hamidy Senior Student Student in Computer Science Kabul, Afghanistan Software Developer Re: SQL or MySQL with c# Henry Minute3-Jan-09 1:49 Henry Minute 3-Jan-09 1:49  There is no 'correct' answer to your question. If you are coding for fun/your own use, use whichever you prefer, for whatever reason you prefer it. It doesn't matter. If you are coding in the commercial world it is unlikely that you will get a choice. On those rare occasions that the customer has no preference you should provide them with an honest comparison of the pros and cons of each system. In my experience that means they will elect to use MS SQL Server because of the perceived (often wrongly) support issues from a non open source product. Honi soit qui mal y pongs - Evil to he who thinks it stinks Re: SQL or MySQL with c# Abdul Rahman Hamidy3-Jan-09 2:35 Abdul Rahman Hamidy 3-Jan-09 2:35  Here in Afghanistan, If you prefer MS SQL Server, then of course the price for that application will increase and if u get MySQL then u have to consider about the performance,replication,recovery and security. My question is regarding only performance, that which one of these two RDBMS provides faster performance. Thanks, Abdul Rahaman Hamidy Senior Student Student in Computer Science Kabul, Afghanistan Software Developer Re: SQL or MySQL with c# Aman Bhullar3-Jan-09 5:21 Aman Bhullar 3-Jan-09 5:21  IF you are using .net as a fron end, then best RDBMS option available is MS SQL. There is a performance gain when we use MS SQL as back end. And the performance gain is not negligible. Regarding cost factor for original. Do not install it on your computer. Have one with web hosting account. Install SSMSE(Its free) on you PC. Connect to remote server and do your job. Re: SQL or MySQL with c# N a v a n e e t h3-Jan-09 16:14 N a v a n e e t h 3-Jan-09 16:14  It's very tough to say which is better. I have a high traffic website which uses MySQL as backend and works like a charm. It gives good performance. But you can gain that only by optimizing your queries and code. Proper indexing also reduces the query execution time. BTW, how are you connecting to MySQL from C#? Is it through Oledb? If yes, that might be the reason for bad performance. Oledb is slow and you should consider the MySQL connector provided by MySQL which can be downloaded from MySQL site. I'd suggest to go with MySQL (5.0 or later).
