Compiler Conditions And Project References?
Jun 15, 2009
I've recently started running into DotNET difficulties with newer HP and Dell systems that are pushing x64 processors and operating systems onto a totally unaware end-user market, so suddenly a lot of work I've done in VB.NET is going to ____ in a handcart; specifically all the work I've done with 3rd Party tools that are only available in x86 or x64 builds and not DotNET Native builds for any CPU. The biggest problem is that all the DLL File Names, in-code Namespaces, Classes, and Methods are totally identical - just one version is compiled for 32 bit and one for 64. What I need to do to fix this is provide some #If compile conditions that alter the paths of existing references based on the Build Configuration, so that when I'm compiling for the x86 platform it references C:DBAPISQLitex86System.Data.SQLite.DLL but when compiling for x64 it references C:DBAPISQLitex64System.Data.SQLite.DLL.
I don't have a problem writing compile conditions, but can't figure out how to alter the reference paths before the compile begins, short of manually removing one reference and adding the other every single time I need to do a dual-platform compile.

For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

Over and over i keep getting stuck on the idea of adding references to a project. I was looking about visual studios 2010, i clicked the project menu tab, and then scrolled to add reference. When i would click on it, it would bring up a large list to choose from. So, my issue is as follows. I am told to reference via my compile error message a few items. I thought i found the elements i was looking for and pressed OK. When i would try to run, it would still give me the errors.
What am i doing wrong? Am i not doing something correct?
here is my error code, and i looked it up, but for some reason, as stated above, i must not be referencing correctly?

I have a project that uses web references to make SOAP calls to several web services. When I'm working locally, the services are hosted on my local machine, so the URL of each web service is something like [URL]. When I deploy the project to a server, the URL needs to change to the production URL. Currently I am accomplishing this with a prebuild event that does a find-and-replace on each URL and overwrites it with the deployment URL before deploying. Surely there is a better way.

I'm migrating data from an old laptop to a new laptop, including some vb.net projects in visual studio 2008. But when I try to open some of them on the new laptop, I quickly get a dialog stating that the vb compiler has crashed and asking me if I want to close, debug, or check online for solutions. Visual studio then, frustratingly, closes.The projects don't crash when opened on the old laptop, and other migrated projects open without crashing. So it must be some property of the projects that becomes corrupted by moving them.
Error Details:
Problem signature:
Problem Event Name: APPCRASH
Application Name: devenv.exe
Application Version: 9.0.21022.8
[code].....
The old laptop is windows xp and uses visual studio professional. The new laptop is windows vista and uses visual studio team. The 'migration' was a straight copy paste of the source files.

VB.NET has this rather annoying limitation which caps compiler warnings reported at 100.vbc : warning BC42206: Maximum number of warnings has been exceeded.This makes things rather frustrating when trying to size up the amount of effort that would be required to comply with VB.NET best practices, such as enabling Option Strict.

I have a winform application written with vb2010.I changed the "Language" property of a winform of my application to german, only for testing purpose. I built the application and in my indebug folder it was created a new de folder with the localized resource file "appname.resources.dll". Then I set back the "Language" property to (Default) and "Localizable" to FALSE and built again the application, but the de folder with its appname.resources.dll were created again. I have controlled each form in my application, the My Project setting too,nothing points to any other culture. I deleted the whole debug folder, but after each build, I get always the de subfolder.I cannot understand what is changed in my application now: why does the compiler create a localized resource if I set back the form properties?I repeated the same for a new culture (afrikaans), to discover any changes in the form properties: I found nothing that could help me, but now I get two subfolders.: de and af

I'm working on a larger VB application (framework v3.5) where the compile time continues to get slower and slower the larger it grows. It currently takes about 7 minutes to compile just the extensions project. We have other similar projects in C# that don't experience the slow compile time.

How is conditional compilation controlled for a VisualBasic web? For a VB Windows app, I put a conditional variable in Project > Compiler tab > Advanced > Custom controls.
How in a VB web app is a conditional compilation variable assigned that can be accessed by all the files of the web app?

Just curious. I recently had an incident in which I was called to troubleshoot a VB Winforms app. I have 2 versions of a package (LeadTools) installed on my machine. These packages contain numerous dlls and it is not unusual for a dozen or more to be referenced in a single program.

I've been passed a solution that has a vb.Net 2.0 project that references to a .Net 3.5 library. The library compiles with out problem but the vb project does not. It complains of missing objects which are in the library which are correctly added in the imports. Also I see a yellow yield sign next to the reference library also when I add the reference it complains of the framework version difference. Any help is apritiated. Also I'm using VS10. Imported the projects with no errors. A colleague has this working on VS9.

I have this VB ASP.NET Web Service Application project running VS 2005. I'm trying to add references. To do so I click on the "Properties" icon in the Solution Explorer window which presents me with a window to add/update/remove references. I click "Add", I select the reference I want and then "OK". Lo en behold, NOTHING! It simply won't add references (I tried adding several different ones). Specifically I'm trying to add the System.Configuration assembly.

In my VS2010 VB project I have a lot of external references to DLLs, to the point that organization has become a major headache and I'm wondering if I am going about it the wrong way. My assembly references include common redistributables (SQL Server Compact 3.5 SP1, ReportViewer 2010 SP1, DataVisualization, as well as some useful 3rd party dlls from CodeProject and CodePlex.
Currently, I am copying each DLL into a 1st level folder (/dll_lib) under my named project folder (under the solution folder), and adding the reference from that path. However, I see that Visual Studio copies the DLLs to various other locations (/bin/debug or /bin/release) in my project when I build the project or solution, and some of the 3rd party DLLs come with instructions to copy them manually to /bin.
What is the "best practice" for where to put the DLLs? Can I just put all of them under /bin and let the build event copy to /bin/debug or /bin/release as required? Should I try to force a single reference path for the dlls in the project output?

This error first appear to occur randomly. Steps to recreate:Open Visual Studio and load a solution (some files automatically opened) - this is when the problem occurs Close all open files Restart visual studio and load solution (no issues)Open Exactly the same files again, restart visual studio and load solution so files open automatically (problem occurs!)
However, when trying to narrow it down to a single file (that is automatically opened when the solution is loaded), I couldn't reproduce the problem. Now with all the files open again the problem doesn't occur!!! So it looks like it is fixed - though this happened before and eventually the issue came back.
I think it is to do with one of the user controls with DevExpress controls on it - when the error occurs, the designer displays the error. Though I can't reproduce it at the moment to confirm that.

If I look at the IL that is created in Linqpad for the two following code snippets, I wonder what happens here.
In c#
int i = 42;
results in the following IL code
IL_0000: ret
whereas in VB
Dim i As Integer = 42
it is
IL_0000: ldc.i4.s 2A
IL_0002: stloc.0
Apparently, the c# compiler understands the the value is never used and thus simply returns nothing. In VB.NET the actual code is translated.Is that due to differences in compiler optimization or is there anything else at work?
Update: Just to clarify this - I just enter this one line into LinqPad and look at the IL it creates (most definitely by running the respective compiler). There is no program.

I added an "edit" icon on my bindingNavigator. When users click on it, a new form will come out and pull out all the data records from the datagridview. Now the strange thing is that when I wanted to edit the data records, when I left the product name blank, I would get an error message saying "Product cannot be blank" - please see above code. But when I left the "Cost Price" blank(same applies to "Sell Price" and "Quantity"), the error message box wouldn't come out, instead, it did not allow me to move on to another textbox, close the form etc until I filled out that textbox with INTEGER. May I know why the error mesagebox would not come out when I entered the wrong datatype?

I am very new to vb, I know there is an error somewhere, I had an assignment which stated that if a number was < 101 or > 500 and the answer is correct the output should be, for example-123, if the answer was wrong then the message output should be wrong number <101>500. Everytime I type in a number(no matter what the number) and click on my check button I get the output message. If at all possible, can you please assist. My professor gave the following example, but I am still not getting it:

Dim dblNumber As Double
dblNumber = CDbl(strInteger)
