vb.net forms error

When I am debugging a vb.Net 2008 windows application and click on the 'next' button, I am getting the following error: 'An unexpected error has occurred. The 'Microsoft.jet.oledb.4.0'provider is not registered on the local machine'. I think that I may need to change some setting I have in the visual studio.net 2008 professional edition to solve this problem. I am working on an workstation that is 64 bits, XP operating system. When the click event has occurred, I have just attached an excel 2003 spreadsheet to a file in the general directory structure prior to

Good bye

Hello, since MS will close this newsgroup on July 1st, I would like to say good bye to you. I got good help in this newsgroup and I would like to thank you all again for it. FYI: For some time I have been using the Community NNTP Bridge and can be found in MS's forums (more reading then writing though). Until today i had no problems with the Community NNTP Bridge and Thunderbird. Maybe it is an alternative for you too. Best regards, Martin

API list on dotnet.

On VB-6 there was a file that has a list of all Windows' API functions (+ types), called API viewer (something like that). It was pretty nice, indeed, including abilities to copy + paste the whole function declaration to VB. but I didn't see it at all on VB.NET. Does someone know - where can I find such a file for VB.NET (or C#, whatever ....) Thanks :)

vb.net classmanager

I am asking for help on compiling a vb.net 2008 application since I have not been able to obtain a successful build with no errors yet. This application that we need to support has no documentation and the programmer(s) who wrote the application are not with the company any longer. This vb.net 2008 solution has lots of project files in it. You can compile this application in the following modes: a.debug, b. debug-test, c.debug-development, d. debug-production, e. release, and there is a class manager configuration file.

Help On Line

Two questions: How can I set helps are on http://localhost:47873 instead http://127.0.0.1:47873? My proxy denied the access to that IP address... Now let me argue... How can I do searches in specific argument libraries? The Help on Line for microsoft seems a synonimous of regression. The Help32 was the best help engine done by Microsoft. Then the chm had cross references that after some searches often wasn't run. With VisualStudio 2005 they introduced a Guide Document Browser where searches were possible, but so hard (whenever you are searching for the description wrote on

DataGridView checkbox.

When I use dataGridView, and one of it's elements is a checkBox. How can I catch the event, exactly when the checkBox is changed. CellValueChanged is not good enough, since the event occurs after both two steps : 1. I change the value of the cell. 2. I move to another cell. I want exactly when the checkBox.checked is changed (DataGridViewCheckBoxCell). Thanks :)

VB 2008 compiling for 32 bit

Hi In VB 2008 there seems to be three places where you can specify x86 or AnyCPU. 1. From the main IDE window, there is a platform drop down box next to the Debug/Release drop down box 2. From the Build Configuration Manager, there is an "active solution platform" at the top of the form 3. On the same form, there is a "platform" option in the grid for each project in the solution. Which one(s) of those matter? Which one(s) actually specify that you are building a project for the 32 bit platform? A semi related question. For a couple of those choices, x86 does not appear as an

Questions about components on design time

I am creating a min-IDE. I appreciate any efforts of helping me going through. You are very kind and patient, especially thanks to Armin. Most of the problem has solved (most of the properties of all the elements can be stored on DB. there are few exceptions) : 1. For nested type (with + sign). I see that their conventer translated the nested types properly, so I can store and retrieve the types with no problem - I didn't see any exception yet, but are there any type you know I must go to inner type (How can I do that : if propertyInfo.propertyType.isNested then ....

use TypeConverter.ConvertToString(aType)

How can I pass a parameter to TypeConverter.convertToString, when aType is, I.e., Color ? If I declare (When I.e the property that is searched is of type : color) dim c as color dim s as string dim converter as typeConverter ..... c = Red s = converter.ConvertToString (c ) The above works ! but when I do : dim c c = color.red s = converter.ConvertToString( c) the above doesn't work ! I didn't find a way to pass the correct type to converter.ConvertString I cannot declare a variable, which is known. I have tried something like c = tryCast(property.getValue(myControl, not

I am using the propertyInfo type. dim pi as propertyInfo pi = myClass.getType().getProperty("myPropertyName", BindingFlags.Public Or BindingFlags.Instance) myPropertyName may be any property, such as borderLevel, etc. I want to set myPropertyName to a specific value, as propertyGrid does (I mean - by sending it a string).

Integer to number, too many decimals

Hi, In a data table I have records numbered from 801 to 809. I also use these numbers as row number then 8.01 to 8.09. To do so I just devide the record number by 100 and put it in a variable of type decimal (also tried double and single). At one point I compare this value with a number to do an evaluation: itemnr = CDec(rw("itemnr")) / 100 "If itemnr = 8.03 Or itemnr = 8.04 Or itemnr = 8.06 Or itemnr = 8.07 Then" Well it should look like that, but it actually showing: " If itemnr = 8.0299999999999994 Or itemnr = 8.0399999999999991 Or itemnr = 8.0600000000000005 Or item

vb.net - office interop

hi there, i try to control excel from vb.net to fill some cells and print a worksheet. after lots of searching everything works - almost: the whole thing works fine when the app is started by an administrator. i get error-message E_NOINTERFACE when running it as normal user. Somewhere in the docs for the office-interop-libs i found a remark 'using the interop-dlls requires administrator privilegs'. i assume, the problem is a dll-usage- or registry-lookup-right. any chance to bypass the admin-requirement for interop-dll? my environment is: vs2008, vb.net, xp sp3, office xp (2002) gre
