• Visual C++ Reading CSV data from a byte array

  I'm writing a C++/CLI (vs2005) app and would like to read in CSV data from a byte array. Is there any .Net classes that I should be using to read the CSV data If not, what are my options Charles Tam wrote: The byte array contains csv data.

• Visual C# Any tips for locating type info file for COM objects?

  Hi, Right now I'm trying to figure out how to get the IDockingWindowSite interface to be available to my C# project. I don't know what file contains the type info that I can import from. The VS IDE has the object browser you can search, but it looks like this only searches loaded types that it knows about. I've ran into this problem before. Please share tips on how to figure this out. Thanks Hi, You can also develop it in C++, then reference the com component in C#.

• .NET Development How do i update table with ID's from user input?

  I want to be able to input what rows (ID's) that should be updated in an UPDATE query. How would you create a UI for this task, and how should i build the query string My previous solution was this: - I created a bunch of textboxes (approx 20), cause i usually did not need to update more than 20 rows. - For each row i needed to update, i filled in the ID in a textbox. Usually, there would be some empty textboxes left. - When clicking a "Update" button I ran a hardcoded a query, that took the values from the textboxes as arguments in the WHERE clause. Example (simplified) "Update Orders SET Status = 'Shipped' WHERE ID IN( "; + txtbox1 + txtbox2 + txtbox3 and so on. Of course, i controlled the data first, and ...Show All

• Visual Studio Express Editions Datbase Search

  I am working with VB 2005 express to create an app that will connect to an Access DB. I have successfully been able to connect the DB to the app and can retrieve data as well. I would like to be able for the user to Input text in a textbox and click a button to perform the search. I am unsuccessful with coding the button to retrieve the records that fit the criteria. If have any solution please could you help me out. Well, I believe it doesnt matter what control you use as long as it supports databinding. Your data details, obtained from a datasource such as SQL, will always be stored in a dataset/datatable. You will be "filling" the data or querying the data from the dataset and then binding ...Show All

• Visual Studio Team System TFS Migration to a new server

  Has anyone been successful in migrating a TFS server to a new machine with a new name We are currently still using the RC, but I was surprised at some of the problems I had during a migration. Specifically Sharepoint, I don't know if its been improved with the RTM, but the restore procedures I saw were just wrong. The 1st trial I did had Sharepoint completely messed up. I finally fixed it, but it took my own understanding of Sharepoint, not the backup\restore procedures provided on msdn. Has anyone else had these issues I'm sorry about the delay in getting back to you, job change sort of had me preoccupied. Short answer, no you can fix it but its not all that nice. Long answer, uninstall TFS, delete the databases (make sure yo ...Show All

• SQL Server Which algorithm is better for customer retention

  Hi Pl any one tell me which algorithm is better for Customer retention Using SQL server 2005 analysis services It will be great if some one can give the same with example of data model with key column , and rest Thanks in Advance Rajesh Ladda Usually you would use Decision Trees for retention, although you may try Naive Bayes or Neural Nets. You model would contain all information about customers and whether or not they "left". You should probably randomly pick an approximately equal number of people who left and people who stayed to get the best results. You model would predict the field indicating whether they left or not. ...Show All

• Software Development for Windows Vista Page Limit?

  Does anyone know whether there is a page limit in an XPS document I have created a 10,000 page XPS document printed with the Microsoft XPS Document Writer from Crystal Reports XI. I can open this document in the XPS viewer with no problems. However, when I create a 100,000 page document using the same package, the XPS document does not open in the XPS viewer and the memory use on my computer jumps and keeps on rising. I am working on Windows XP. Any ideas, anyone The problem you're experiencing is a bug in the implementation, not the limitation of XPS format itself. This will be considered for a future release. If you're blocked by this issue, try to write or find a tool which can repair ZIP files. ...Show All

• Windows Forms [C#]Datagridview copy/paste from a row to another row

  Hi all. Before opening this post, i've already spent a lot of time looking for solution to this problem over the net and over this forum :( I only need to copy some values in a datagridview row, and paste over another row of the same datagridview. Thx a lot in advance at all :) Bye and have a nice day, RaouL. Hi. First of all, do you only need to copy within your application If the answer is "Yes", you could do away with using the clipboard and set up some kind of buffer in memory. You would copy the data under your copy event into the buffer (if other things like cell formatting are required, you would handle the various formatting you would need in separate buffers, sort of like layers in a ...Show All

• .NET Development How to handle data in different tables?

  I was wondering if someone could point me to a tutorial that might help me I have an application that I'm developing that will display a tabbed form which needs to contain data from different tables. For example, my database has a contact table with typicall information and then it also has a lead table which contains information if the contact is a sales lead. They are linked together by a common contactID column. There are a few other normalized tables also like an AlternateAddress table. My first problem was that I could only get the binding source to connect to a particular table. This was a problem cause the data that I need to modify is normalized across a few different tables. My solution to that problem was to create a view ...Show All
