Notepad has nothing to do with it, it's just a program that reads text file. System.IO.File.ReadAllText is the easiest way to read a file.

THERE IS NOTHING WRONG WITH THE CODE!! You're using SendKeys to send this data to another application, which is notoriously unreliable! The value of the variable is NOT changing when you call SendKeys. The problem is that your destination application isn't cooperating with SendKeys! Is there anything you can do about it?? Short of seeing if you can get an updated version of the target application, no, there isn't...

SO THE PROBLEM NOT THE DISTINATION BECAUSE I USE THE FUNCTION IN MANY TARGET APPILCATION ... I THINK THE PROBLEM IS THE DELAIY .. I NEED TO KNOW HOW I CAN DELAIY THE FORM WHEN I MINIZE IT .. THIS IS THE LAST CHANCE TO USE IT ...BECAUSE THE PROBLEM THAT IT PRINTS ALL STRING IN SMALL PERIOD LESS THAN 1 SECOND kilany Re: i ask you too much Dave Kreskowiak26-Apr-06 1:11 Dave Kreskowiak 26-Apr-06 1:11  If you can't send keys to Notepad properly, I'd say you have a problem with your system. notepad is nothing but a glorified TextBox control. During this entire time, you never once mentioned WHY your trying to control another application and even WHAT that application is. I've already said that you have to look for other methods that are reliable, like an SDK or COM component for that application. Now, you've just about run out of time to look... Dave Kreskowiak Microsoft MVP - Visual Basic Re: i ask you too much Christian Graus25-Apr-06 10:01 Christian Graus 25-Apr-06 10:01  There is no level on which you can send one number and recieve another. It's got to be the way in which the number is being handled in code. What's send ? Are you using WM_COPYDATA to send stuff between applications ? If not, what are you using ?

It's just not the right way to go. You have options that are sensible, mainly the ones I listed when I asked. You never answered, BTW, without Dave's comment I'd be even less able to help you. The best help I can offer is to scrap what you're doing, and do it properly. Christian Graus - Microsoft MVP - C++ set selectedvalue of combobox that is bound to dataset G7236025-Apr-06 3:32 G72360 25-Apr-06 3:32  Hi, In my application I have a form with some comboboxes on it. These comboboxes are all bound to different datasets. When the form shows, I can select a different index in the combobox, the text is adjusted as expected. To here, I encounter no problems. In some cases, when the form is loaded, I want to select a value in the combobox that I obtained by accessing my database. Example of my code: cboIncidentType.SelectedValue = curIncident.IncidentErrorType Now, for some reason, the selectedValue is not set to what I define in my code, but to the first index in the combobox. Can someone tell me what the problem is? Thanks! G72360 Re: set selectedvalue of combobox that is bound to dataset Dave Kreskowiak25-Apr-06 9:53 Dave Kreskowiak 25-Apr-06 9:53  This depends on when this code is being called. If you're doing this at the beginning of the Form_Load event, the ComboBoxes haven't been filled yet... Dave Kreskowiak Microsoft MVP - Visual Basic Re: set selectedvalue of combobox that is bound to dataset G7236025-Apr-06 11:25 G72360 25-Apr-06 11:25  The comboboxes are filled before the selectedValue is set. When selectedIndex 0 is returned, the datafield (text) of index 0 is shown, only it is not the index I tried to set. G72360 sqlexpress 2005 deployment problem User 91483325-Apr-06 3:17 User 914833 25-Apr-06 3:17  I have icluded an SQL database file in my application and it now uses sqlexpress to attach that and use that file. It workes good but now I have to deploy sqlexpress 2005 with my application and it requires SP2 for Windows XP. Is there any other way I can use this SQL file without forcing all the customers to install SP2? Any help is good because I'm desperate. --Nikola-- modified 7-Dec-20 21:01pm.

Nope. It's the minimum system requirement for 2005. An older version MSDE, like MSDE 2000, on the other hand, doesn't require SP2. This will, of course, depend on your applications requirements.

Re: sqlexpress 2005 deployment problem Dave Kreskowiak26-Apr-06 1:25 Dave Kreskowiak 26-Apr-06 1:25  MSDE was the predecessor to SQL Express. The name changed when 2005 came out.

VB.Net Generated Code MikeUPMC25-Apr-06 2:59 MikeUPMC 25-Apr-06 2:59  Is there a way to override the code that vb.net generates for Deletes, Updates and Inserts? The code generated is slowing down my app for these functions, especially for only 1 record. I'm using the BindingNavigator controls to add, update, delete, etc. PPOBindingSource.EndEdit() PPOTableAdapter.Update(Me.DwCustomDataSetPPO.BenefitAdj_PPO) Is there someway to over ride what Vb generated and create mo own code for these functions? The generated code is inefficient and convoluted. Any help greatly appreciated. Mike Regarding Deploying a web application Vijaya Krishnamoorthy25-Apr-06 2:11 Vijaya Krishnamoorthy 25-Apr-06 2:11  Can any one tell me how to deploy a web application?... where as the web application module uses a web service for some applications... thanks with regards , K.Vijaya CausesValidation and ControlBox paas25-Apr-06 1:54 paas 25-Apr-06 1:54  Developing a windows application with VB.Net under VS 2005. I am wondering if anyone knows how I can prevent validation events from firing if the user clicks on the control box close button to exit a form. I do not want to set the CausesValidation property on all of the form controls to False as I do want validation events to fire if the user is tabbing from control to control. However, the control box close button presents an apparently ugly issue because, when clicked, not only does the validation event for the control being exited fire but the FormClosing event still fires even if the validation event fails and the program issues a Cancel. Has anyone else run across this problem and found an elegant solution? Thank you... Re: CausesValidation and ControlBox paas25-Apr-06 4:09 paas 25-Apr-06 4:09  Well, the most "elegant" solution I've come up with so far is that the cancel property of the FormClosingEventArgs is set to True at the start of the event when a control just failed validation. So, I can check that property and if it is set to True as soon as the event starts, just skip any other code in the event. I would feel better about this solution if I could trust Microsoft not to change the behavior of CausesValidation to something that actually makes logical sense in a future update or revision. If anyone thinks they have a better solution, please let me know.
