I have an aspx page that my colleague designed for me to stick on the back end. I made a few alterations to the page, adding various controls and things - and now the compiler doesn't recognize any of the controls on the page! The Intellisense is working just fine - I can type txtName. and as I push the . all the properties of a TextBox pop up as normal.ut when I try compile, the compiler says "Name 'txtName' is not declared".

I've added two labels to my form, named them appropriately, and then went to the code to do my thing.Intellisense is not picking up the 2 newly-added controls! I opened the .Designer.vb file for the form and I can see they are in there. I tried "cleaning" the project as well with no luck.

which compiler errors would be detected out by VB compiler?
I have searched out some compiler errors list for C#, for example, see the website at [URL]
MS provided us the information about C# compiler error. Does MS provide VB compiler errors information as well.VS

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 would like to know the vReasons why vb.net 2005 is not recognizing changes when there are no errors. It does not capitalze and tab a new entry. When I try to debug it just goes to the previous debug not the current one.
View 4 RepliesI've never worked with VSTO and I've recently read all kinds of stuff about it. So I ask a theoretical question. I'm trying to make an addin which should (using buttons in it's own ribbon tab) upload the document to my website (it's like slideshare). The problem is that this file may be already uploaded and the user may be just trying to update it.
So I need a way to tell if this file has already been uploaded. I know the prediction can't be 100% accurate, that's why I'm going to ask the user with a dialog, but I need it to be fairly clever to alert the user if the file MAY BE is already uploaded.
This assumption can be client-side only, with a database of some sort (in the addin itself).I thought of recording the file's name and based on this I can decide if the file is new or it's already uploaded.
PS. Working on Office 2010 with the latest version of VSTO in VS 2010. My main .net language is VB but samples in C# are more than welcome (if you have ones).
I have this database with different kinds of Date formats. I can have:
01 Jan 2009
Jan 2009

How can i Recognize witch date format it is? And if i have found it out, How can i split it on the space?

View 4 RepliesI have been working in Visual Studio which has DevExpress. My project now doesn't recognize DevExpress so I now have 102 errors on lines like:[code]...
In addition to this when I try to go to the designer for my DevExpress report it can't load the designer :
"The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: rptAll --- The base class 'Object' could not be loaded. Ensure the assembly has been referenced and that all projects have been built."
Yet when I look in my toolbox the DevExpress tools (XRLine, XRLabel...) are still shown and DevExpress is still located in my reference folder.

The basic idea is to find <BODY> tag and look what's after it till the </body> tag, is that possible?
I have a query that executes fine in TOAD, but when bringing back the results with either an ADO.Net DataReader or DataAdapter/DataSet, it's not recognizing a column in the select statement. See the query below... the column in question has its data coming from a dynamic table or sub-select or whatever you call it. I don't see why this is a problem in .Net:

View 4 RepliesIm making a little game. All it does is make a bunch of Random Letters. Move around the screen. Im drawing to the form with paint. But i wanted to make it. So you have to click the letter that my program ask's you to click. I know there is easy ways of doing this. Like just getting the x,y and the mouse x,y on the click event. But i was wondering. If i could accomplish this task. Just by Scanning about 10x10 pixels from where the mouse down event is triggerd. to see if a letter is there. And how i could make it see if it is an A or B etc. The font is white. And about this size. I was thinking about it counting all the white pixel's but that wouldn't work?

View 6 RepliesThis is VBA6.5.1040 using an Excel 2007 (12.0.6524.5003) SP2 MSO (12.0.6529.5000) spreadsheet. The aim is to use a cell in which one can type "Y" or "N" in answer to a question. Before proceeding, the code forces the user to choose one or the other (section B). This works perfectly well. I then added the code in section A so that the user could type "y" or "Y". It would then convert "y" to "Y" and the code would proceed as normal, and similarly for "N". However, the following code in section A produces: "Compile Error: End If without block If," and high-lights the first 'End If'.

I have an click once application. The prerequisites which i have mentioned is .net Framework 2.0. If the prerequisite is not there in publish.html, i get a button to download it, else the Run button will install the application (which is developed by me) . This works fine in all the machines, except for one in which i have the following versions of .NET Framework,
.NET Framework 3.0 Service Pack 2 3.2.30729
.NET Framework 3.5 SP1 3.5.30729
.NET Framework 2.0 Service Pack 2 2.2.30729
In this machine even though we have Framework 2.0 and higher versions, i am getting the button to download Framework. This is not correct.

View 11 RepliesVisual studio 2005 - vb.net..I have a user control on a form containing 15 combo boxes.All contain Y, N, and blank (for Yes, No, or blank) in the Items Collection property.Each of the combo boxes have a binding source to the same table, different fields.When you select a value Y, N, or blank for any of the fields and do a save, the values save while the application is open.Once you close and reopen, the values are gone.It appears the dataset does not recognize the change, so the values are not getting stored in the database table. Is there something I can do or put in one of the events that would identify this as a change.

how to create my own programming language,I can create a compiler for a language like vb.net itself. Essentially, the user inputs code, they get a .exe. By NO MEANS do I want to write my own language, as it seems other compiler related questions on here have asked. I also do not want to use the vb.net compiler itself, nor do I wish to duplicate the IDE.
The exact purpose of what I wish to do is rather hard to explain, but all I need is a nudge in the right direction for writing a compiler (from scratch if possible) which can simply take input and create a .exe. I have opened .exe files as plain text before (my own programs) to see if I could derive some meaning from what I assumed would be human readable text, yet I was obviously sorely disappointed to see the random ascii, though it is understandable why this is all I found.
I know that a .exe file is simply lines of code, being parsed by the computer it is on, but my question here really boils down to this: What code makes up a .exe? How could I go about making one in a plain text editor if I wanted to? (No, I do not want to do that, but if I understand the process my goals will be much easier to achieve.) What makes an executable file an executable file? Where does the logic of the code fit in?
This is intended to be a programming question as opposed to a computer question, which is why I did not post it on SuperUser. I know plenty of information about the System.IO namespace, so I know how to create a file and write to it, I simply do not know what exactly I would be placing inside this file to get it to work as an executable file.
I am underway to develop a VB.Net compiler using visual studio 2005, but so far I am not aware on how to go about, regarding to what are the key requirements or skills required for developing a compiler.
