i have a very regular problem with MS Access showing random results when being written to from Visual Studio 2008. It happens on all computers including the development machine, using Vista or XP, VS 2005 or VS 2008.Is there a VB.Net flush command I can use before reading the data ?.I write data to a table and then immediately go to read that data.I can make it work if I wait up to 3 seconds before I read the data after a write, using a sleep command. Unfortunately 3 seconds is way too long.Are there any known problems with writing data to MSAccess 2003 from .Net, using VS 2008, VB.Another weird thing that happens is that only half the data is there if I write to an Access table and then go to read it immediately. Sometimes the data's there, sometimes not, with the exact same code and data.
Sometimes the whole table fills with the data from the first record.This is happening throughout my code. Anywhere there's data being written to Access there's a problem if I go to read it immediately after.Sometimes the Access table is blank, even though data has been written to it, and then on a second run of the exact same code it comes good, or gets half the data or every record is a duplicate of the first record. The code is good, so it's not a coding problem, and I can run the exact same code and get good results. So it's definitely an intermittent problem.I run all my access writes through the same code. The part of the code that writes the data is "command1.ExecuteNonQuery()". Whether I read the data from a datatable or as a merged word document, I still get the same problems. So I'm guessing that there's a problem

I have a program that outputs a file. I want the user to be able to just double-click the output file and launch the program, just like Word and Excel. In Word for instance, one doesn't necessarily have to open WORD then click on File--> Open and locate another Word doc. He can just go to the folder and open the Word doc. I want to implement the exact scenario in my program.
So far I have tried creating TextFile and added it to the Resources. On FormLoading, I simply I stream-read the Resouce file, but I can't write to the Resource on FormClosing, since the Resource is ReadOnly. Also, the Resource is built & compiled so I suppose you can't add anything to it at run time.How you lunch an output file without launching the Executable program that created it?
I have an executable that I was able to get working on all XP machines by registering all the .dll's associated with it.On Vista, however, I go through the exact same registration process but right when I open the executable it goes to a "WindowsApplication1 has stopped working" dialog. I registered the DLLs in the SysWOW64 folder. I also ran Dependency Walker which came up with IEFrame.dll as flagged, don't know if that is relevant though.
View 6 RepliesI have an application that has file extensions associated with it. The application has been deployed using ClickOnce. I have checked the associations table to confirm the entry is there and the association is to the 'ClickOnce Application Deployment Support Library'. When the application is triggered using a file with my extension, it does not pass the filename / directory in the CommandLine Arguments, instead you get the executable path of the application.
Which is under ..LocalSettingsApp"Random Strings"MyApp.exe
I have checked the Registry entry to confirm what the extension is set to open with and the application is dfshim.dll. Is there a way to overcome this, or is this just another limitation of ClickOnce deployment?

I Actually want to provide a new service which requires creating executables on the fly from executables generated in vb.net. For example lets say I have a form with a textbox and in that textbox we pass an argument which is for example the serial of the product, then we have a button which once clicked will generate an executable on the fly which has also a textbox requiring that serial to run? That was only an example but the main thing is how to generate that exe on the fly.

Im working on a HSD 32 bit data bus to serial converter via a microcontroller. Now first I want to make a sort of data sniffer to read the data bus (32Bit) .All on the controller side is working and the stream of bytes are coming in via RS232 as 4 bytes in HEX like FD,A5,45,8B . I already converted the bytes in Dec and ASCII to determine what is passed true the bus and how fast and stuff.. Now that is all correct and working very well if the LSB (least significant bit) of the 32 data bus is Data line 0 and the MSB (most significant bit) is Data line 31 but if that is not the case I need to invert the 32Bits (like as I would invert the connector on the bus) . How do I best do this using the 4 bytes I send from the micro controller.
Example:
(MSB) 01001000 01100101 01101100 01110000 (LSB)
HEX= 48 65 6C 70
DEC= 72,101,108,112
ASCII= H E L P
I need to invert it with a button to:
(MSB) 00001110 00110110 10100110 00010010 (LSB)
HEX= 0E 36 A6 12
DEC= 14,54,166,18
ASCII= (SO) 6 : (DC2)
