I'm having trouble dragging a record from a linked file. The structures for the three files
Customer File:
First Name
Last Name
Address etc
[Code]...
how do i then display all the records in the booking file, in a listbox - but to also populate the relevant details from the other files. Example: after displaying the Customer ID in the booking file, to get the first name and last name from the customer file.
Got a problem that's hopefully a quick fix. I've got a homework assignment where I have to link an access database file and allow the user to go through the records, add/delete records and save the file.
When I run the program everything seems to work fine, except when I hit the next button to go to the next record, it always skips 2 ahead, from 1 to 3 and 3 to 5. The previous does it also and when I click the delete it deletes 2 records. I can't figure out why it's doing this. The table we linked was already created for us so I don't believe that it is a problem with that. One weird thing I noticed is that it shows that there are 5 records so I wouldn't think that it is seeing 2 as 1.
Here is my code for the buttons:

I cannot get the dragdrop event to fire when I drag a file from one tabpage to another tab page in the same tabcontrol. I can drag a file from my application and drop into windows explorer and and then drag from windows explorer into my app. That all works fine. And when I drag from one tabpage up to the top of the control, my program uses the tabcontrols dragover event to swap tabs....works fine also. ...Drag drop event fires...no problems
Say I have a list box with files on one tabpage, a list box with files from a different directory on another tabpage, I want to be able to drag the file over and drop it into the other listbox.I have done lots of testing on the variables in the dragdrop handlers to see if they are recognizing the switch in controls and they are. But the dragdrop event will not fire.

View 7 RepliesIs there a simple way to read from the global application.exe.config file from a dll?urrently I am loading the file as an XmlDocument but I wonder if there is a better solution.That's what I mean:If I create a new WinForms Project I have a Settings Tab in the Project properties where I can add some simple values (And I want to access the per Application settings, not the user beased ones).From my code I can access these values with:
Console.WriteLine(Properties.Settings.Default.SomeValue);
The Settings class is autogenerated in the file Settings.Designer.cs.Now I have the case where a dll need's to read the settings from the Main Application's config file. Is there a simple way to achive this? Currently I am reading the file as an XML Document.
I would like to create a little list in my Windows Form showing a list of custom colors with their 'friendly names'. Technically it can be anything (ListBox, ListView, Panel etc... whatever).
I simply want it to look something like this:
I would like to store data for this list in a simple TXT file in such form:
Quote:
Blue,Blue
Red,Red
#F6A118,My favourite color
#004080,Another color
And of course I would like each element on such list to be clickable, so if I'd click 'My favourite color' it should return the color's HEX value (#F6A118).
Im wondering how would i work with a text file. which would allow me to Read the next Record, Cut record out of the program.
View 15 RepliesBasically, I am making a booking system. On one of the forms, you can: Add, Edit and Delete a record by using the selected index. I can do the Add and Edit part fine but some problems are occuring when I try to delete it. What I'm trying to do when deleting is, copy all the records except the selected one and then copy it back into the original file again.

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?

In previous versions of VB, you could drag or move the form to a convenient spot on the IDE. With 2010 express, the form is in the upper left hand corner and will not move. The toolbox essentially hides it.I have not been able to find a setting that changes this condition.

Im working on 'Virtual iPod Touch' project and I'm almost done..but one thing annoying me..im using drag 'n' drop to make lock slider..1 got 1 picturebox with lock arrow and 1 black (transparent/invisible) with allowed dropping...and its all ok but I want only I can slide (move mouse) in area for sliding (see a picture, but I think all of you understand).
View 12 Repliesthe user has the option of dragging several pictureboxes around the form. when he lets go of the mouse, the picturebox will take on a new position on the form.
i would like to implement the following:
on mouseup, if the picturebox position is within some amount maybe 50 or 100 (i dont know what units VB.net) uses, i would like it to be dropped exactly in a defined position. sort of like if you play checkers on yahoo games, you dont have to place the piece exactly on the square only approximately.
Been a while since i've bothered you gentlemen with my questions, but im back! So, I want to know, how I would be able to drag a picturebox around a form, liek a drag and drop functionality, but I dont want to move folders. Just move it around the form.

Right now I have checkboxes on my form, and depending on what check box I check, the value of it gets put into a text box. So if I check "Right Eye", the texb ox below it gets "Right Eye" placed there.
I would like to do away with the check boxes and instead have a new form pop up with a list of words that gets populated from a table. Is it possible to be able to drag and drop these words into a text box? I guess I could use a List Box control for that but I'm unsure how to implement drag and drop. Maybe be able to multi-select words and then drag them all to a certain text box.
I'd like to have give the user the option of adding and deleting words from that form as they see fit, so could I just let VS do that for me by dragging the datasource onto the form and have it create a bindingnavigator or should I do it myself?
I am currently working on a flatfile based database, meaning: all database records are saved in single files in a data folder of my main application. So far everything works fine except for one thing:
Each record gets currently saved as file under its item name. This sometimes causes problems because some item names contain special characters which can't be used as a file name. What I would like is the following: Whenever I 'add a record' to my database it should be saved in a file with a 4 to 6 digit number as file name - to keep things simple I just ignore the file extension for now.
For example, I add a new record with the ITEM NAME Flower "Blue River" #1 - I won't be able to create the file because of the special characters in there! I would like that the program creates automatically a file in a 4 or 6 digit format (I haven't decided yet how many digits because I am not sure how many data records I will need one day, so, 4 digits will be enougth for now!), starting at 1000, so, the file I am creating is called 1000 + whatever extension I will give it later.
In addition, I would like that it checks for missing numbers in between when creating a 'new database record', meaning: I have already the folloing file names: 1000, 1001, 1002 and one day I delete the second record, so, 1001 would be available for the next new file / data record which I add to my database.
So far I've experimented with the GUID but the filenames I get out of it are just not in an 'eye pleasing' format. Would there be a way to give this GUID a special format or is there any other good way to accomplish that?

I'm working on a little program that uses a ListView box. I'd like to know if you can arrange the list by dragging the items within the ListView box. Example: I'd like to be able to just drag the bottom item to the top, or the middle item to the bottom, and so on. I guess I'm just wondering if I can move items around using the mouse by dragging them around within the ListView box.

I have a datagridview showing data from an Access database. I have dragged the datagridview from "Data Sources" window - and not written any code. In bindingsource I have choose to sort on an autonumber field. Is it possible to let the user use the mouse to change the order, and the database to remember this the next time the user starts the application.I guess I have to have a number field in the database, and write code to change the value in number field as the user change order - and then save this back to the database? Does the datagridview support changing order by mouse at all?
