• Windows Forms How to install windows and web application using a single setup file

• Windows Forms refresh the data table disable to select

It is disable and not allow to select, how to fix it thx table desc: 1 unique primary id no special character I have also had problems with getting the identity to reload when added to the database.

• Visual FoxPro CHM Help in VFP9

  Hi All, We have an application that we recently upgraded from VFP 8 to VFP 9. The transition was smooth except that the help file of the application is not working in VFP 9. I have made sure that FOXHHELP9.exe and FOXHHELPPS9.dll are included in the installer. After doing some research on the web, I read a comment on http://fox.wikis.com/wc.dll Wiki~VFP9RuntimeFiles which only says: foxhhelp9.exe /regserver When we type thi command at the cmd prompt, it fixes the problem. However, this is not the solution our users want to see. Can you please let me know the reason for having to type this command, and is there a way I can avoid going this route Thanx, Bini The installer for your EXE (in VFP9 generally ...Show All

• Smart Device Development Sending packets out UdpClient on Motorola Q Smartphone

  K, thanks to Ilya, I'm making definite progress. I've now got lots of nice debug output going to a TextBox. I'm now trying to send a packet out a UdpClient. A call to Send seems to return successfully but I see no packet emerge on my Ethereal trace of the network interface. Likewise, there is no response coming back as expected. This despite the fact that I can see both web requests and DNS queries and responses going back and forth, obviously bound for the phone over ActiveSync. The UdpClient is bound to port 5060 (SIP for those that may not have guessed already). I have turned off the Windows Firewall. Any other ideas about what might be blocking this packet Thanks, FM OK, so I just discovered that Act ...Show All

• Visual Basic For your VBA, CUT AND PASTE the Function out of this VB.Net code.>>

  Hi! I have a list with prices of US Treasury bonds. They are quoted in a particular way that I would like to convert to decimal form. They are quoted like this eg: 99-02. Now this means that the price is 99 and some decimal. The two first numbers are the number of 32:s. Thus in this case the price is 99 and 2/32. However if there are three decimals eg 99-021 the last digit refers to the number of 124:s. Thus the price is 99 and 2/32 and 1/256. Sometimes There are only two decimals followed by a plus or minus sign eg 99-30+ or 99-10-. The plus/minus indicates that you should add/subtract 1/64. Keep in mind that the non decimal numbers may be one, two or three digits. Thus, it could be eg. 6-02 87-22- or 105-21+. Is there any wa ...Show All

• .NET Development how to unzip a file in .net 2.0 with C# as a language

  I have a zip file.I want's to unzip it how can i do this in .net 2.0 as we know there is a class i think gzip from which i can unzip a file. Please can anybody help Hi Kamran, The short answer is that the .NET libraries don't provide a way to easily unzip a zip-formatted file at the moment. And working around this takes a bit of effort. First I'll give you an overview of compression in .NET and then give you pointers to possible workarounds. As of now, the .NET compression libraries support at the core only one compression method, which is Deflate. Our GzipStream class, for example, is Deflate plus some extra header info and checksums -- i.e. the GZip format defined in RFC 1952. Many other compressed file formats besides gzip ...Show All

• Visual Studio Team System MDX syntax question

  Hello, I am starting to play with customizing some of the TFS Reports and have been able to create a couple of simple ones on my own. I am just trying to get my head around MDX and learn the basic syntax by playing with some of the box reports. I am having a simple problem however and I don't understand what is wrong. I am trying to modify the Remaining Work report and add in a filter in the WHERE clause that only returns items where the Exit Criteria is set to false. i.e. [Work Item].[Microsoft_VSTS_Common_ExitCriteria].&[Yes]. So my modified query looks like this. ---START WITH MEMBER [Measures].[Date Key] AS [Date].[Date].CurrentMember.UniqueName SELECT { [Measures].[Date Key], [Measures].[Cumulative Count] } ON COLUMN ...Show All

• Visual Studio Team System TSql Tests Timeout

  I am writing tests for procedures and the tests have pre-test and post-test actions that may run for well over a minute, and I periodically receive the error "Failed <TestName> <TestProjectName> Sql Error: 'Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.' (Severity 11, State 0)" when I run the tests. I typically receive the error about 30 seconds after starting the test.

• Software Development for Windows Vista IVMRWindowlessControl9.GetCurrentImage returns black frames.

  Hi, I am extracting frames from a DVR-MS file created by Vista Media Center. It works fine but sometimes IVMRWindowlessControl9.GetCurrentImage(IntPtr iDIB); returns a black frame. If I run the graph and pause the thread of my application for a second and get than the current image - it works just fine. So it looks like it needs a few ms to get the frame etc...
