• .NET Development Navigating Large Database

  I have a SQL database table with about 1,000,000 records. I would like to be able to view these records on a form, linked to textboxes and such, and be able to navigate through them, as in back and forth. I have tried using the dataset and it is extremley slow to load the dataset. Its so slow it would not be usable. Does anyone have any suggestions on how I would be able to navigate through these records You should only pull a set (lets say 1000) records at a time and when the user starts to get to the upper or lower limit of your displayed records you fetch the next (or previous)1000 records. This is the most efficient means of navigating through large amounts of data...Your user can't view 1000 records a ...Show All

  Hi, I am doing R&D on the features of Windows Workflow Foundation which we are going to apply for our project after release of WWF. we are using SOA Architecture. So I need to call services based on the rules. I have succeded in doing them practically using Sequential and State Machine Workflow. So, now I want to achieve Asynchronous way of calling webservices. I don't know whether this can be possible with WWF or not. If it is possible, can any body please help me in doing this. Thanks in advance. Hi matt, In ur reply you have mentioned about local service, is it local webservice . If it is so I have created a webservice with one public method and an event, like the following [ Serializable ] public class R ...Show All

• Visual C++ Single vs Multiple dlls

  Hi, I am building an ATL COM DLL component. There are many functions to be exported (around 100). I want to ask about the performance gain/loss in case I build a single DLL exporting all functions or in other case build multiple dlls. Thanks & Regards, Omer Javed If all functions are used in the same client, it is better to keep them in one Dll. Loading one large library to memory is faster than loading number of small libraries. ...Show All

• Visual Basic Bringing in FORTRAN dlls using DLLimport

  I'm having a problem getting some unmanaged code to link into a program I'm writing. I have some FORTRAN legacy code that I don't have the option of rewriting, and I need to link several pieces of it together, as well as create a GUI for it. I've created a wrapper class for it using a DLLimport statement and I keep running into the following error: System.BadImageFormatException was unhandled Message="An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)" Source="FORTlib" where FORTlib is my wrapper class. The code is attached, the mentioned dll is the dll named in the code, called "readFile.dll". Surprising I know. This is a very simple piece of code, I' ...Show All

• Visual Basic format text box on the fly

  I've got a textbox and the user would enter a dollar figure in it... How can I format the figure so it shows properly i.e 100000 is entered and after he leaves the box i want it to show $100,000.00 Mitch How about using Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Leave TextBox1.Text = FormatCurrency(CInt(TextBox1.Text)) End Sub This will format for the currency on the machines. For looking at other formats the following gives some good examples. http://msconline.maconstate.edu/tutorials/VBNET/VBNET01/vbnet01-08.aspx ...Show All

• Visual Basic Determining Max Unique ID in a Project File

  I am coding a Visual Studio 2005 VB.NET Windows Application. VBA answers may not apply. MSProject.mpp files contain tasks. Each task contains a UniqueID (an integer) which increases as per the rules of AutoNumbering... it is a database primary key. If I want to search for a specific UniqueID, I cannot rely on TaskID numbering since the two are generally independent. Therefore, generally, the value of the latest consumed UniqueID will be greater than the number of the last task number in the file. The following code will not compile producing the error message: "Access of a shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated" SourceFile = Fo ...Show All

• Visual Studio Team System Process for updating production databases

  I have a question for the db pro process gurus. Once our product has been intially deployed to production we face the challenge of releasing incremental builds. On previous projects I have used automated schema comparison/script generation tools (redgate, db ghost). I haven't found a tool that was able to correctly identify what the changes from development to product were from iteration to iteration. My preference has always been to have DB developers code manual scripts for the updates so it gets them in the mind set of "how will this change affect production " I don't trust the build/deploy process to accurately generate the changes that I have made within the project. I have found you can get production and development way ...Show All

• SQL Server Report Execution timeout after 60 minutes (1 hour) - Execution cannot be found (rsExecutionNotFound)

  Dear Colleagues I wonder if you could help me. I have a report that runs for from 0 to 1,5 hours when executed. If the report executes and renders output file in less than 60 minutes - it works fine, but if only it takes more than exactly 60 minutes to run it generates the following ASP.NET exception: ReportServerException: Execution 'lmxn1q3k3zdxwjvavsargonw' cannot be found (rsExecutionNotFound) At the same time if I make a subscription to save report for example to network share it does not stop at 60 minutes and saves data to the required folder (I've scheduled it this night and the report was saved after 1,5 hours of execution).
