• Windows Forms DataGridView Filter

  Hello, I'm using DataGridView to display about 50,000 records. I've added a filter to the dataview, tried to use various implementations, but all of them work very slow (same implementation on  .net 1.1 gave a much faster performance). I've tried RowFilter, RowCount, etc. I understand that there is an option of using VirtualMode in DataGridView for a large number of records, but have found no way of filtering when using it... Can you please direct me to the right direction of increasing the performances, or maybe tell me where am I wrong Thanks, Marina I'm not aware of what changes have been made in ADO ...Show All

• Visual C++ Getting Error - Regarding stdafx.h

  I'm trying to fool around with the new Visual studio version (2005 Beta 2) and for some reason it keeps telling me: \Practice.cpp(1) : fatal error C1083: Cannot open include file: 'stdafx.h': No such file or directory A long time ago someone told me to go into the properties of the project and change the default to CLR support.

• Visual Studio Team System DeclareEventHandlersCorrectly

  TypeName: DeclareEventHandlersCorrectly CheckId: CA1009 Category: Microsoft.Design Message Level: Error Certainty: 95% Breaking Change: Breaking Event handler methods take two parameters. The first is of type System.Object and is named 'sender'. This is the object that raised the event. The second parameter is of type System.EventArgs and is named 'e'. This is the data associated with the event. For example, if the event is raised whenever a file is opened, the event data typically contains the name of the file. I have two questions : Why must the arguments be named "sender" and "e" Why must the ...Show All

• Visual C++ sqrtf under 24 bit floating point precision

  Hi, While trying to estimate performance impact of using 24 bits floating point precision versus 53 bits, I've noticed that sqrtf function was 6 times slower in 24 bits control mode. Every other operation I've tried (divide, exp, cos, ...) are all faster or equal in 24 bits mode compared with 53 bits mode. How could this be explained Are there other math functions or instructions that will suffer using 24 bit mode Regards Guillaume Unfortunately, I don't believe there is a list somewhere. I believe default mode should take care of the perf issue per the above description of the issue by the ...Show All

• Visual Basic Rename a Table in MS Access using VB or SQL statement

  Hi all, How can I rename an MS Access table in VB or thro' SQL statement I have 2 clues as given below, but I am not able to get to use these ideas. These statements does not seem to refer the ADO library and hence, I do not know how to arrive at framing a program for these statements.

• Visual Studio Express Editions .cfm vs .xml

  Is the main difference the empty white space lines at the top before the "< xml version = 1.0" These empty white lines are giving me fits, when I read in data from the .cfm file which is supplied to me. I get err: ""< xml version = 1.0" must be first node". I wrote a routine that strips these empty white lines. Then it works. But doesn't VB2005EE have code that handles .cfm files directly Surely, others have run into this Hi Jonbu, Since .cfm files are proprietary to one of Microsoft's competitors it shouldn't be a surprise that we don't support them directly.

• Visual FoxPro Grids are readOnly. How do I put text in them?

  Hi there. Kind of embarrassing asking simple question when other people post such advanced requests. I am new here. I got as far as creating a form with two grids and other controls I need. There is a Pageframe that switches between pages and I have each grid on the corresponding page. All the way I am making comparisons with dBASE stuff which I hope soon will be a thing in the past. Anyway, when I run the form all rows in grids appear to be read only. I cannot enter any information in any columns. I want preempt a question about the tables.

• Visual C# Digital signature

  Hi all, I'm looking for materials and links about digital signatures. Also tutorials dealing with this topic. Please help... Although not written in C# (it's written in cross-platform compatible C), it would probably be worthwhile to look at the source code and docs for Gnu Privacy Guard (GnuGP) , which is a free version of PGP. Years ago, PGP (Pretty Good Privacy) , developed by Phil Zimmerman, was a great free solution for encrypting and/or signing files. If you're not familiar with PGP or the OpenPGP standard, I would recommend spending some time on Wikipedia reading about it. ...Show All
