I have an idea and can code, if someone can get me moving in the right direction. What I have in mind is running a program when it is loaded. No Start buttons or clicking. Just running when it loads. I have looked on the Internet and in books I have purchased, but am unable to ascertain the command or code to run a program when it loads.

-Save all the tab's texts from a tabcontrol
-Save contents of the tabs : eg.Every tab contains a label and I save the text of each label
And the real problem:
-Loading them when the program opens
I have made some thoughts about saving them, but not about loading them

I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.

View 6 RepliesI'm trying to use a loading overlay on top of a Windows form that adds a 50% opaque layer on top of a windows form with a loading GIF, while it does what it needs to do in a background thread. The overlay is a windows form that I'm drawing in the onPaint event.
The loading overlay works fine on multiple different form loads, but fails to work properly when summoned to ensure patience during a 30 second upload process (That Prints a Word Document to PDF, then uploads that PDF to a SQL Server). This upload collects some data from the form, puts it into an Object, then operates entirely on a background thread. The loading overlay will appear, show the first frame loading GIF, then just freeze. The onPaint is getting fired and the image frame is being updated, but it isn't visible
Constructor sets the form to be UserPainted:
Sub New()
InitializeComponent()
SetStyle(ControlStyles.UserPaint Or ControlStyles.Opaque, True)
End Sub

I've spent hours trying to get this simple test case working, and searching the internet for clues.
I have a VS 10 solution containing my VB.net project, and a VC++ DLL project.
In my DLL project i have:
json_main.cpp:
#include <Windows.h>
extern "C"
[Code]....
I tried using dumpbin.exe on my DLL, but I don't get any function names out of it to determine the mangling scheme it is using
Trying to exit an application but can't seem to kill it without an error."An error occurred creating the form. See Exception.InnerException for details. The error is: The form referred to itself during construction from a default instance, which led to infinite recursion. Within the Form's constructor refer to the form using 'Me.'"The form hasn't loaded yet, it is still in the process of looking for a file to load, if the user doesn't want to specify a working directory, that is their choice, but I need to close the app since it can't continue without it.I'm stuck in a class and can't get back to the main form without it continuing to load everything up. I wan't to force a shut down. [code] I was trying to get back to the main form without loading any more from the class to kill it there. [code]
View 6 RepliesI'm trying to make my program have plugins that don't require real installation. My plan is to have the plugin consist of two files:a dll file, and a xml file describing the dll so the program knows what to do with the dll. However, I have NO idea where to start.I've referenced dlls and used them in my program before, but that was BEFORE compileing the program. Could someone please point me in the right direction?

View 1 RepliesI have been working on a solution that uses Combo Boxes to fill DGV I have 3 RDM tables, 3 Combo boxes and 1 DGV Probably best way to explain tables is this way
Table 1 OwnerID 1, 2, 3, 4, 5 ( There are 5 owners)
Table 2 CDID 1=(1,2) 2=(3,4) 3=(5,6) 4=(7,8) 5=(9,10) (each Owner has 2 records)
Table 3 CDTrackID 1,1=(1-10) 1,2=(11-14) 2,3=(15-20) 2,4=(21-27) 3,5=(28-36) 3,6=(37-40) 4,7=(41-44) 4,8=(45-47) 5,9=(48-55) 5,10=(56-60)
where 1,1=(1-10) means
Owner 1 record 1 has 10 records and
Where 1,2=(11-14) means
Owner 1 record 2 has 4 records
etc etc
On Form Load Combobox 1 loads all the data from table 1 with no output in DGV (Works well) (5 records Perfect)
When I select a record from Combobox 1 it loads relation data from table 2 into Combobox 2 and also displays same in DGV (Works well) eg if I select record 3 in combobox 1 it loads records 5 and 6 into combobox 2 and DGV (2 Records. Perfect)Now comes the Problem When I select a record from Combobox 2 it is supposed to load the relation data from table 3 into ComboBox 3 and display same in DGV eg Combobox 2 has records 5 and 6. If I select record 5 It should load 3,5(28 - 36) OR If I select record 6 It should load 3,6(37 - 40) instead If I select Record 5 then Record 1,1(1-10) loads into combobox 3 and DGV If I select Record 6 then Record 1,2(11-14) loads into combobox 3 and DGV Regardless of which record I select from Combobox 2 (1,2); (3,4); (5,6): (7,8); (9,10) it always loads the same records into combox 3 and DGV Sample code for combobox 1
SQL = "Select * From CD Where OwnerID-1 = '" & cbxOwner.SelectedIndex & "'"
Sample Code for Combobox 2
SQL = "Select TrackName From CDTracks Where CDID-1 = '" & cbxCD.SelectedIndex & "'"
[code]....
The only thing I can think of is that my query constantly sees 2 records and numbers them as 1 and 2 thereby displaying records 1,1(1-10) OR 1,2(11-14)?
I have a CSV file which I append using the LoadActivityLog sub and then I pass this CSV to a datatable and populate a DataGridView in my form using the WriteAcitivityLog sub. Everythign works fine. However the datatable passes the information into the datagridview in such a way that it populates the column header rows with data as well. I want to put custom column header fields into the datagridview. However i cannot figure out how to do this.

I'm sifting through the dump of AniDB titles and everything works except that it only sees 7161 elements instead of 9200. Anyone have any idea why? It's not calling an exception on the load method as if something is wrong. Even when I change it to just take the root element and then get the count of children, it gives 7161. Like it doesn't even see the last 2000.
