I recently created a deployment project for my windows application in Visual Studio 2008, and have found that changing the "Remove Previous Versions" property to True does absolutely nothing. When clicking the installer, it will say a previous version is installed, then immediately quit.
View 2 RepliesI'm reasonably familiar with the various forms of VB that existed prior to .NET (VB6, VBA, VBScript...), but have yet to delve into The Sweet New Flavor that is VB.NET.
View 6 RepliesThe software I design is for Win XP and older versions such as Win 98, ME, 2000 etc. I currently use VB6 and Win XP for development and packaging, the problem I encounter is that if I use the deployment wizard in XP, the setup will only work on an XP machine and I need to copy all my source to an older machine and use the wizard again to create another setup file which will only work on the older operating systems. Is there a way to rectify this in VB6? If not, does the new VB account for this and be able to make a setup file for older operating systems as well as XP?

View 1 RepliesI'm writing an Excel file recovery program with VB.Net that tries to be a convenient place to gather and access Microsoft's recommended methods. If your interested in my probably kludgy, error filled, and lacking enough cleanup code it's here: http:[url]..... The basic functionality seems to work although I haven't tested graph macro table recovery yet.
It occurred to me that Vista and Windows 7 users could benefit from being offered a list of previous versions of the file within my application if the Shadow Copy Service is on and there are previous copies. How do I do this?I looked at a lot of web pages but found no easy to crib code. One possibility I guess would be to use vssadmin via the shell but that is pretty cumbersome. I just want to display a dialogue box like the Previous Versions property sheet and allow users to pick one of the previous versions. I guess I could just display the previous version property sheet via the shell by programmatically invoking the context menu and the "Restore previous versions choice", however I also want to be able to offer the list for Vista Home Basic and Premium Users who don't have access to that tab even though apparently the previous versions still exist. Additionally if it possible I would like to offer XP users the same functionality although I'm pretty sure with XP only the System files are in the shadow copies.
I looked at MSDN on the Shadow Copy Service and went through all the pages, I also looked at AlphaVSS and AlphaFS and all the comments. I'm kind of guessing that I need to use AlphaVss and AlphFS and do the following?Find out the list of snapshots/restore points that exist on the computer.Mount those snapshots.Navigate in the mounted volumes to the Excel file the user wants to recover and make a list of those paths.With the list of paths handy, compare with some kind of diff program, the shadow copies of the files with the original.Pull out the youngest or oldest version (I don't think it matters) of those shadow copies that differ from the recovery target.List those versions of the files that are found to be different.This seems cumbersome and slow, but maybe is the fastest way to do things. I just need some confirmation that is the way to go now.

If I create a DLL using VB 2010 express can it be used by previous versions of of .Net (3.5, 2.0)? Will the DLL use .Net 4.0 components, which is what I want. I don't see a way to force that to be the case.
View 1 RepliesTo the board: Lately I've been getting Runtime error 3447 ("The Jet VBA file (VBAJET.dll for 16-bit versions, or VBAJET32 for 32-bit versions) failed to initialize when called. Try reinstalling the application that returned the error") when attempting to open a certain program (not one that I designed, just downloaded and installed). I installed this program in January 2009, but this error began happening only this past July. someone else to information about the files vbajet32.dll and expsrv.dll. One site said that the problem was probably caused by the file expsrv.dll being absent, but I checked my System32 folder, and it's there. As far as I can tell, it has always been there (the computer was made in 2008, and as I said the program had always worked before). Vbajet32.dll is also there. I tried uninstalling and reinstalling the program, but error 3447 still occurs. I also tried uninstalling the program and installing an older version, but 3447 is still there.
I tried replacing expsrv.dll, thinking it might have been corrupt, but that didn't help, and I cannot register that dll anyway. I can't figure this thing out. Both of the files are there, and I didn't change any settings or anything anywhere between last January and this July. By the way, I am on Vista.
The default installation of my setup project is as follows:
[ProgramFilesFolder][Manufacturer][ProductName]
The problem is PC in Europe don't have a "Program Files" folder, it's in a different language.When I remove [ProgramFilesFolder] from the setup program, the installation doesn't work. I would like to install the application in C:AppFolder,
In Datagridview, Set as DatagridView1.ReadOnly=True,
Dgv1.Rows.Add()
When i tried to add a Row, it is copying previous Row data to new row,and also blank the previous row, why?Like Insert Row, Why...?
What I want to happen is that the button from my system will remove the previous data from database and then insert new data to database from text file. Im done with inserting new data. The thing is that I dont how to control or where to put the Delete Command from my code.

I am deploying sql express as a prerequisite. I have created a custom prerquisite using bootstrap manifest generator.

I have a windows app that uses the shape control which is part of the MS power pack and requires Microsoft.VisualBasic.PowerPacks.Vs.dll. I am using Publish to build my app and I have tried to change the dll to Include in the properties page but nothing seems to work.

Have built a project and associated it with a Setup&Deployment Project. The S&D project needs to contain 2 main folders (under User's Desktop) with various formats of files (xmls, txts, dlls) inside them and several subfolders. How can i copy/import these 2 folders and there sub-files/folders into my s&d project?
When adding them in the usual way, they are copied and defined a source path onto the current pc. You can understand what errors this might create when an another targeted pc does not contain those files to the exact location. Is there any way to copy them locally or somehow import them?

I am developing a plugin into a third party control. They ship a SDK dll with their application to allow you to do this. However I am writing the plugin using version 1.1.0.0 of their SDK, but when trying to run the application on a clients machine that has a new version of the software the SDK version is 1.4.0.0 and my app throws the following error:
System.IO.FileLoadException: Could not load file or assembly 'MyDll.dll, Version=1.1.0.0, Culture=neutral, PublicKeyToken=764d581291d764f7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
When the dll is referenced into Visual Studio I have changed the Specific Version property to false, however this has not made any difference. The dll is not reference from GAC.Is there a way that I can tell my application to just use the version of dll that is on the users machine? I have checked with the 3rd party vendor and the functionality that I am using has not changed in any of the versions as they use a back-ward compatibility approach to their software.
I have a dataset that I export to xml (using ds.WriteXml) and then use an instance of Microsoft.Office.Interop.Excel.Application to open and manipulate the xml data, then save it as an .XLS file.I have office 2007 (why don't they have help/about in an easy to find place... man I hate those stupid office ribbons and the person who developed them...)Anyway, this code works fine for me. But when I put this on a machine that has office 2003 installed, it crashes.So, what do I need to install, reference, buy, etc. so that I can do the same thing on machines that have 2003 (or before) installed? No, I can't install office 2003 (my first thought).
View 8 RepliesI have an application that uses a Microsoft DLL (Microsoft.ComponentStudio.ComponentPlatformImplementation.dll) which is used for OS deployment and accessing the catalog files. Version 6.0.0.0 is specific to the Windows Server 2008 catalog files. The newer version 6.1.0.0 is specific to Windows Server 2008 R2 catalog files. Attempting to access a catalog file with the incorrect version results in an exception.
My application (VB.NET using VS2005) needs to be able to access either version of these catalogs - I'd be happy with two executables (one for each catalog version) but obviously I don't want to maintain two sets of source code for each. Specifying both sets of DLLs in the project reference is not possible as the DLL names are identical. I'd rather not have to manually add and remove the DLL references each time I want to a build. As far as I know the interfaces etc are effectively identical between the two.

I have a .net Application that writes text to a serial COM port, a POS reciept printer to be more exact. i am using the Rs232 class library to write and read to a serial device.My problem is now with some clients that have updated their operatingsystem to WIN7 64bit version, have trouble to create a connection to the COM-port. the com-port seemes to get occupied with some other process and that blocks my application to opening a new connection. so for my question, does anyone know how i can close all connections to a com port? or see whats blocking it? once again this seems to only to affect win7 and 64bit users.
View 1 RepliesI have a pretty complicated project with lots of class files, code modules, etc. There was a changed to one of my referenced DLLs that requires an isolated change in a single Sub within my solution. Unfortunately, this new Sub is not compatible with most of my clients' configuration but is required by some of my other clients. So now I must keep two versions in Source Safe of my solution - which I do not want to do. What I would like to do is to be able to determine which DLL is running and flip a switch to use the either the old Sub or the new Sub. Currently the sub is in a class, but I could break it out. Is it possible to determine which assembly version DLL is running? Also, if I reference the new DLL, the old Sub will not build. If I reference the old DLL, the new Sub will not build. So is there a way to keep both Subs in the same project?
Can I use reflection to know what is the assembly version of a loaded DLL?
