View 25 RepliesI have a program that reads the version of a program off of a txt file in the program folder and off a txt file hosted off a site and compares them. If it's different it downloads the update, if not then you can use it. My problem is when I update it. It doesn't replace the version in the file. How would I update the version on the txt file in the program folder when it gets updated.

View 7 RepliesI have an application I've written for some of the people at work and there is one bug that I have no idea how to solve. The application is multithreaded so that the main form can be updated with new information as it comes in. Throughout execution, several other forms come up as well (one at a time).Every so often I get reports that the program freezes. When I check out the program it looks like the main form is not being updated(checkboxes are see through, textboxes are blank) and the main form can't be moved around. This only seems to happen sometimes when the program is left for long periods of time (+30 min) and only on the released .exe and never in the debugger(as of yet). I've tried leaving the program running overnight and it had no problems.

I'm looking for suggestions on keeping a program that is running on a network updated. Installation consists of 15 users, each have the program on their local pc, but they all access same date from sql server. I am looking for a clean method that would allow me to update one folder on the network and for each computer to get updated when they run the program and the programs sees a later ver on that folder on the network. (Obviously I can do this inside the program itself since it won't allow being overwritten while opened.)
View 3 RepliesI want to work on a project I have in mind and this envolves saving data which would need to be updated every time the user exits the program. I suppose I need to know how to save a file to a blank text document, and how to get the application to read the information when it is called for. I believe I need to set delimiters or such, the helpfile is useful, but limited and some information is not listed at all.

Whenever I change a user setting in app.config (via running the program) the change doesn't appear in the app.config file (it stays the same). When re-running the program, however, the change is reflected in the program's behaviour. How can this happen if app.config wasn't altered when the program was last run?

I have an issue with a data table that I have updated using the datatable.update command.The datatable is bound to the datagridview using dgv.datasource = datatable.I have used INSERT and UPDATE commands and the INSERT command writes the data back to the database ok. However my problem is that it the dgv is not updated with the primary key (ID field) from the database. So when I save a second time, instead of updating it just inserts the data again.
[Code]...
I have run into a problem with saving to database when running the program I am making.
I have an mdf file called prices.mdf and have set the "copy to output directory" to copy if newer setting and set this for the ldf file build action is set to content.. should it be compile or a different setting??
I access this database thru a dataset called pricelist dataset and when the program runs and you go to forms to update the prices, each form has a datagrid with the toolbar and the save icon. Mostly I followed tutorials to help me put it together.
When you run the change price menu for each part of the database, they appear to save each time u re run the program. But once you close down vb2010 and reopen it a day or so later and rerun, the new prices are gone and the old prices are being used.
I thought changing the setting on the mdf file to copy if newer is the usual fix for this, but as I said I have already got it set to copy if newer.
I can't figure out how to track what the dataset is accessing to make sure it is going to that database, or if i have made some sort of other database that it is accessing instead as well as the mdf database.
when I look at the dataset and the column entries for each part of the prices database, as to whether i need to check the dataset itself, or the forms the datagrids are on with the toolbar save icon, or whether there is another place to check to see if it needs to be changed to something like change if newer.
Obviously the program is working and doing the changes, but not storing them in the right place, so I am losing the changes once i shut down my project and reopen it.
also I have looked at the file propertiesand made sure they all set to copy if newer PricelistDataSet.xsd, pricelistdataset.designer.vb, and also the pricelist dataset.vb, xcs and xss ones are all set to copy if newer when I look in the solution explorer.butsome of the build part is set to compile on some and none for others As I am not experienced with VB 2010 or databases I am not sure how to track it down
Update: Just looked under each of the forms the data grids are on. and see the copy to output directorys on these are set to do not copy for each of the designer.vb, vb and resx. I am bit hesitant to change these without getting some advice from more experienced people if the forms also need to be set up to copy if newer.
This is what is shown in the coding on one of the forms if u double click on the save icon in toolbar
