I am trying to develop a small hotel booking application to be just used by a single user. What would be the best way to store the hotel bookings in the program? I've been thinking between an XML document or a SQL database but im unsure if a sql database would work on a pc without any sql software installed (complete sql noob >.<) or would their be an easier way of storing them?
View 2 RepliesI am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --

View 6 Repliesyou can use the My.Settings that VB.Net 2010 can offer. Go to Project > Project Name Properties > Settings and there you can add variables. The value of the variable is saved even after you close your program.A program that will show the text you saved last time is the following:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If My.Settings.X<>"" then MsgBox(My.Settings.X)

View 4 RepliesHi, I need to program a simple Web Browser that can search for keywords and store relevant data in another file.I am facing a problem with authentication, mainly cookies and maintaining a session.So I read that Web Browser Control is based on I.E.? So may I know how are cookies and session handled?Do I have to implement them manually or are they stored and retrieved from the same folder as the one used in I.E? If so, if I delete the I.E.'s cache, am I also deleteing the cache of any Web Browser I make using Web Browser Control?

I have an application that uses Dataset.WriteXML to create a small backup before data is syncronized to a data store (less than a meg).This application has worked well for 5 years now, and all of a sudden with the installation of XML 6.0 SP2 the XML document is not working correctly.I have multiple tables within a Dataset (Company, Contact, Notes, etc...)When WriteXML is called, the first table should be Company, however, the first table is being named Contact with the Company Data in it. The Notes table is being called Contact and so forth. In other words it's not giving the correct names to the tables in the XML File.This appears to be a bug, which is causing great distress on all the companies who have been using this program.

View 1 RepliesIn the program I'm working on, there is a 'sign-in' form that pops up for the user to enter first name, last name, and DOB. What I want to do is STORE that information in a text file for FUTURE use by the program (i.e. displaying a list of all previous users of the program).I already know how to use streamwriter to write text to a file, but I would like for the text file to be stored within the program files and also for a new user's data to be appended to that file every time.
Do I simply add the text file to the project files? When I do that, its path is 'My Documents'. How will that affect the program when I publish it? I guess I just don't yet understand what happens when the program is finished and published. The code for the 'Submit' button on the sign-in form is pasted below. At the bottom, I've put a comment to indicate where I want to store the data to a file.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim TxtBox() As String = {TextBox1.Text, TextBox2.Text, TextBox3.Text}

So I got this program to generate me some data and I want to show that data to a label.
If I don't do a display I can generate about 20,000 data per second, but if I do, I get about ~9,000 data per second.
PS. Since the generating logic in is a thread, I have a function that does the displaying to the label.
Here is what I would like to do:
- Store string data from a 'sign in' form into a text file. This text file must be one that is saved even after the user exits the program. The text file must also be one that will stay with the program even after it is published (executable).
- Be able to write to/read from the file for purposes of displaying some or all of that data on a form.
I use an Application Setting to do this - of type 'Specialized String Collection'. I tried this, but for some reason I could not get it to work. It was a good idea, but I need to be able to SEE the data that has been saved, and with a setting it seems like that is not easily done. I've decided that I either need to use a simple text file or a 1-table database for this. I would prefer just a text file, but in either case, it needs to be part of the .exe when published.
I have added a text file to my project, but I am not sure if it will be "included" in the project when I publish it. The path of the file I've added is in 'My Documents', but in my code, I will have to specify the path in order to use Streamwriter. How will this affect the program when I publish it? I felt the need to make a new thread because on my last one we had been mainly talking about settings, and I've decided that isn't the best option for me.

View 3 RepliesI am having a problem storing an image as a Blob in a SQL linked table. Our system uses an Access 2002 frontend and linked to a SQLServer2000 database. I have a form that I want to display a unique client jpeg photo for each client record. Our client HIPAA concerns means we have to store the image not the path in the database field. I am using an Image control on the form. Initially I have been able to load an image from a Windows Dialog into the control and save the path no problem.
My issues are surrounding how to actually save and load the jpeg as a BLOB in a VBA byte Array after the image has been loaded to the form from the dialog box.(Is there some sort of binary conversion needed or does the Append and GetChunk methods handle all this)?:
All the code examples I have been able to find on the subject have a line of code to set the Image control's data source to the open recordset with this statement ---> Set imgDBImage.DataSource = rs. Does this statement work with VBA because DataSource does not show up as a property of an Access 2002 Image Control. So how do I point the Image Control to the table field which contains the BLOB in VBA code?
Finally, how do you convert the string path of the image to binary for storage in a byte Array in VBA. I have the syntax for a VB 6.0 which is..... .Fields("ImageBLOB").AppendChunk bytBLOB. Is the .Fields portion of the code relevant in VBA to tell what table field to write to and does the AppendChunk method handle all the conversion?

View 3 RepliesI'm wanting to store some settings for my program in an XML document. I've found plenty of places that allow you to write an XML document to somewhere on the hard drive although I'm wanting to link it in with the project so when the program installs it setups up the XML as well. This is also so when the program uninstalls it removes the XML.So I was wondering how I would go about writing to the XML document in my project, could it be done with Linq?

It is a temporary workaround.When I do press button3, I get the incomplete hex number, instead of "4C00A2C82A0C", I get "A2C82A0C", and sometimes I get random digits like 1,A,C etc etc.

I hope this is the correct place to obtain a little bit of advice for a program I am looking to produce in visual basic 2010.
I currently work as a design engineer designing press tools and a lot of our designs are similer just maybe a feature, length, diameter change etc. So the design principles are the same for each product.
What I am aiming to do is program the 3D design package so that 80% of the tool design can be done using the program etc.
Now the enquiry I have is where would the best place to hold the standard data be?
For instance each press has a maximum blank diameter, shutt height, bores diameters in the bed and likewise each product type has design features with the same calculations such as length, pierce etc.
I have done a bit of reading and I have found that data can be stored into text files, xml files and databases etc or hard coded into the program.
I am looking to allow new presses to be added so the user would need to add new shutt heuights, blank size etc but the tooling would have to be unqiue dependent on the typs of stage. So I am wondering to store this information would a database be the best option even though the data will not be continually updated more a place for it to be retrived from excpet under failry rare circumstances.
I was thinking about using an access database to store the data but I would like to know if there is a better way of storing data?
