Am using version of 2008 Express (Trial)need to connect to a MySQL 5 DB from VB.NET [2008] 3.5 Framework from code.when i try am getting ystem.Resource.MissingManiFestResourceException
View 1 RepliesI am building an application for windows mobile 5.0 using the .net compact framework and the mysql compact framework connector.Using this very simple app, I test the connection to our database:
Dim connection As New MySql.Data.MySqlClient.MySqlConnection("Server=160.10.1.25;Uid=***;Pwd=***;Database=DevAutomate;Pooling=false;")Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
connection.Open()
connection.Close()
End Sub
In the beginning, I was using an emulator to test this and I was getting a MissingManifestResource error. When I figured out that the emulator didn't have a network connection, I connected it to active sync and used the device emulator manager to simulate cradling the device. Next, I got my hands on a HP iPac mobile device running windows windows mobile classic and I get the MissingManifestResource exception again. This time, I have a network connection on my device and it can definately see the database.
I have used the "using" statement in both C# and VB. I agree with all the critics regarding nesting using statements (C# seems well done, VB not so much)
So with that in mind I was interested in improving my VB using statements by "using" more than one system resource within the same block:
Example:
Using objBitmap as New Bitmap(100,100)
Using objGraphics as Graphics = Graphics.From(objBitmap)
End Using
[Code].....
My gut tells me that if the resources are related/dependent then using more than one resource in a using statement is logical.
I have a function which uses MSXML to post an Xml document which yesterday started failing despite no change being made to the code. The function is as follows:[code]The Xml document and the address being passed in are both correct - the line which causes the error is xmlHTTP.send(xmlDoc). I have tried this on 2 different machines with the same error each time, and have also tried resinstalling MSXML3, with no success.[code]
View 1 RepliesI'm writing a program that I want to attach another program (.exe) to. I tried adding it as a resource, but I can't seem to get the resource to export out to wherever the program is running.
View 3 RepliesI need to refer to some strings using an "indirect string" in the registry. It should be in this form:
@filename,resource
MSDN: "If the resource value is zero or greater, the number becomes the index of the string in the binary file. If the number is negative, it becomes a resource ID."How can I find out either of these numbers for my resources that only have names in VB? I also need the ID/index for the exe's icon.
I have a resource file that I include in my shared code library that has all of my re-usable classes in it (all the resources go into their own namespace). Now, what is the best practice regarding resources... should I include them in the same DLL, or should I have a seperate resource DLL and/or are there any benefits from seperating them out into their own file.
View 8 RepliesSo i created resource file New --> new file --> Native Resource Template Then added icons with custom id, like "x", "u_100", .. so i understand, what the files (in my case icons) is.. And i saved as 32-bit resource file (*.res) So i have a question, how can i use these files inside of resource file in my apps? i know how to add icons in to my app.. Me.Icon = New Icon(C:/icon.ico)

I am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work. It will all work fine until I attempt to run or debug the project. The data will not show up. The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
As I said, the project seems to build fine, but it will not pull the data. After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?
I have a utility that is a simple exe that is not installed compiled with VS2005 and works well. But when I upgraded to VS2008 the utility can no longer locate files in the active system folder. I have UAC turned off and am logged in as the Administrator and it still can not locate a file that I can see in Windows Explorer. The file I am looking for is PakMgr.exe.

Here's the code:
Timer declared as private member variable.

The timer has to have a value or else the Timer.Stop() call would be throwing the exception. This is a sporadic error and I'm just trying to see if anyone has experienced this before or if anyone has any ideas of what could be causing it. It is occuring in a WinForms application in the event handler for the Elapsed event of the Timer, but it is only occuring sporadically on the users computer. I haven't been able to reproduce the error myself.
I wrote the code below which calculates the length of a line on the form and save record. An error occurs when the programme tries to save the record. It gives me "Cannot perform '=' operation on System.Int32 and System.String" error. I checked the data type of "ID"(int), "Microscope"(Varchar), "Magnification"(int) and "Calibration"(Decimal), and they are fine so far as I know.
